Citadel Paint Storage Guide: How to Organize Every Pot from Base to Contrast
Citadel pots are 32mm wide and need 33mm rack slots. Standard 26mm racks designed for Vallejo won’t fit them. Complete Citadel paint storage guide for every line from Base through Contrast.
Citadel pot: a flip-top paint container 12ml in capacity and 32mm in diameter, standard to Games Workshop’s entire paint lineup. The rigid plastic design and wide footprint are distinct from dropper bottles, requiring purpose-built storage with 33mm+ slot dimensions.
Flip-top lid: the hinged closure design exclusive to Citadel pots. The lid remains attached to the pot when opened, preventing it from being lost during painting sessions. Citadel’s 32mm width means PROSCALE’s 33mm-slot racks are purpose-built for Citadel compatibility, accommodating the entire paint range from Base through Contrast.
CITADEL PAINT RANGE OVERVIEW AND THE MULTI-LINE CHALLENGE
Games Workshop manufactures six distinct Citadel paint lines, each engineered for specific painting stages and applications. Unlike Vallejo’s ranges, which vary mainly in thinning level or medium, Citadel lines differ fundamentally in formulation, opacity, and pigment load. Organizing a complete Citadel collection requires understanding these differences because they affect both storage density and workflow.
The Base range is the foundation layer paint — high opacity, quick-drying, formulated to cover primer in a single coat. Base paints are core inventory for any Warhammer painter and typically represent 40–60% of a Citadel collection. A complete Base range runs 70+ pots.
The Layer range is for highlight and detail work — lower opacity than Base, slower drying, designed to layer over Base without obscuring previous colors. Most Layer colors correspond to a Base color (e.g., Base Averland Sunset + Layer Yriel Yellow = highlight progression). A serious Warhammer painter owns 50–80 Layer pots.
The Shade range — formerly called Washes — is for depth and definition in recesses. Shade pots are smaller than Base and Layer (9ml instead of 12ml), but they occupy 32mm slots identically. Shade colors are highly specialized — only 20–25 in the full range — and most painters own 8–15 shades depending on their color palette (reikland fleshshade for skin, agrax earthshade for everything else).
The Dry range is for speed-painting highlights and weathering effects. Dry paint is chalky, extremely low-opacity, and fragile — it damages easily in storage if pots are tipped or stacked. Dry pots should be stored upright and undisturbed. Most painters own 10–20 Dry colors.
The Contrast range is Games Workshop’s newest paint system — semi-transparent acrylic engineered to pool in recesses and create depth automatically. Contrast pots are physically identical to Base pots (32mm, 12ml) but the paint chemistry is unforgiving if mixed with other Citadel lines. Contrast pots should be stored separately from Base and Layer to prevent accidental cross-contamination. A Contrast collection typically runs 20–35 pots, though competitive painters may own the entire 40+ color range.
The Technical range covers specialized effects — metallics, weathering, texture pastes. Technical pots vary in size (some are 12ml, others 24ml) and require careful upright storage. Most painters own 5–10 Technical pots integrated into their main collection or stored separately depending on frequency of use.

POT DIMENSIONS AND HEIGHT VARIATION ACROSS CITADEL LINES
Citadel’s dimensional consistency is a curse and blessing. All pots are 32mm in diameter, meaning any 33mm+ slot rack fits them. But the heights vary substantially, creating visibility and access challenges.
Base and Layer pots are 18mm tall — the standard height. These are the workhorse pots, and most Citadel racks are engineered around this dimension.
Shade pots are 12ml instead of 12ml Base pots, resulting in a pot that is visibly shorter — approximately 14mm tall. When mixed in a rack with Base pots, Shades sit lower in their slots, making them slightly harder to spot during color selection. However, the difference is subtle enough that many painters don’t reorganize specifically to separate Shades. If a rack is designed for 18mm-tall Base pots, Shade pots fit the slots without issue, just less prominently.
Contrast pots are identical in height to Base pots — 18mm — making them visually consistent in mixed-slot racks. The difference is purely chemical; visually, Contrast pots appear identical to Base pots.
Dry pots are noticeably shorter and stockier — approximately 15mm tall with a wider body. The shorter height makes them visible but distinct. Many painters deliberately segregate Dry pots to their own rack section because the fragile paint requires special handling (no stacking, no horizontal storage).
Technical pots vary widely. Standard Technical pots (metallics, washes) are roughly 18mm tall and fit with Base and Layer. But larger Technical pots — texture pastes, mud effects — run 24ml and are significantly taller. If a painter owns even one 24ml Technical pot, a rack designed strictly for 18mm Base pots will have that single tall pot protruding.
The practical solution is to select a 33mm-slot rack with 20mm+ internal slot height — this accommodates all standard Citadel pots (Base, Layer, Shade, Contrast) plus most Technical variants without adjustment. A rack with adjustable internal height or modular slot depth handles outlier Technical pots.
CITADEL PAINT LINES: DIMENSIONS AND SLOT REQUIREMENTS
| Citadel Paint Line | Volume | Diameter | Height | Required Slot | Visibility in 33mm Rack |
|---|---|---|---|---|---|
| Base | 12ml | 32mm | 18mm | 33mm | Full |
| Layer | 12ml | 32mm | 18mm | 33mm | Full |
| Shade (Wash) | 9ml | 32mm | 14mm | 33mm | Slightly lower, visible |
| Dry | 12ml | 32mm | 15mm | 33mm | Visible, shorter profile |
| Contrast | 12ml | 32mm | 18mm | 33mm | Full |
| Technical | varies | 32mm | 18–24mm | 33mm | Variable height |
A 33mm-slot rack accommodates all standard Citadel lines with identical width compatibility. The height variations are subtle enough that visibility remains excellent across the entire range. When a painter organizes a Citadel-only collection, slot width is no longer a decision variable — all Citadel pots are 32mm. The organizing axis shifts to line (Base vs Layer vs Shade) or color family (reds, skin tones, metallics). A painter with 80 Citadel pots can reach for any pot with confidence that it fits the rack securely.
CITADEL LINES AND STORAGE SEGREGATION STRATEGY
Three organizing principles compete for dominance when storing Citadel paints.
The first principle — organize by line — separates Base, Layer, Shade, Contrast, and Dry into distinct sections of the rack. This approach is excellent for painters who work methodically through a model: apply Base, then Layer, then Shade, then highlights. Each stage has its own section, and the painter moves sequentially. A Warhammer painter building a Space Marine army this way benefits enormously from line-based organization. Finding all relevant Layer shades for skin requires glancing at one section, not scanning the entire collection.
The second principle — organize by color family — groups reds with oranges, all skin tones together, all metallics together, regardless of line. This works better for painters who jump between techniques or who work on multiple models simultaneously with different color priorities. A painter speed-painting five different miniatures with different color schemes can identify needed reds across all Citadel lines without switching visual context.
The third principle — organize by model or project — dedicates slots to specific armies or painting campaigns. A Necron army might occupy eight slots (four layers of metallics, shades, technical effects), a Space Marine army another ten. This works for committed painters managing one model at a time but breaks down quickly if the painter’s attention spreads across multiple projects.
Most successful Citadel painters use a hybrid approach: primary organization by line (Base in rows 1–3, Layer in rows 4–6, Shade and Contrast in rows 7–8), with secondary organization by color family within each line. This dual axis handles both sequential painting workflows and color-matching speed equally well.
CONTRAST PAINT STORAGE AND CONTAMINATION RISK
Contrast paint’s chemical formulation — semi-transparent acrylic with different flow and pooling behavior — is fundamentally different from Base and Layer. Accidentally applying a Contrast pot to a Base pot, or vice versa, creates unpredictable results. Most painters either store Contrast entirely separately or mark Contrast pots distinctly to prevent confusion during painting sessions.
Full segregation is the safest approach: a dedicated 33mm-slot rack or wall section holds only Contrast pots, isolated from Base and Layer. This adds cost and wall space but eliminates the risk of cross-contamination entirely. A painter with 30+ Contrast pots can visually scan their dedicated Contrast rack without cognitive overhead.
Integrated storage with visual markers works if the painter is disciplined. A single rack holds Base (rows 1–3), Layer (rows 4–6), and Contrast (row 7), but Contrast pots are painted with a distinct marker color on the lid — white paint marker on the top, for example — making them instantly identifiable during painting sessions. This works for painters with 15–20 Contrast pots who are unlikely to grab the wrong pot in the speed and chaos of active painting.
Shared slots without segregation is viable only for small Contrast collections (under 10 pots) where the painter has perfect recall of which pots are Contrast. Most painters don’t, and mistakes occur. Not recommended.

CAPACITY PLANNING AND CITADEL COLLECTION GROWTH ARCS
Estimating the size of a Citadel collection requires understanding the painter’s commitment level.
The beginner collection — a painter starting with a Warhammer starter set — typically contains 20–25 pots (Base colors, a Shade, maybe one Layer set). These fit easily in a compact 60-slot 33mm rack.
The hobbyist collection — a painter maintaining one active army — runs 80–120 pots total (50+ Base, 30–40 Layer, 10–15 Shade, plus Technical). This collection requires a 120-slot rack or slightly larger. Most casual Warhammer painters plateau here.
The competitive collection — a painter fielding multiple armies or competing in tournaments — spans 150–200 pots. This includes the full Base and Layer ranges (70 + 80 = 150 pots before Technical), plus dedicated Shade and Contrast sets. This requires two full 120-slot racks or one large modular wall system.
The completionist collection — a painter who owns every Citadel paint ever released — exceeds 300 pots easily (Base 70 + Layer 80 + Shade 25 + Contrast 40 + Technical 30 + duplicates of heavily-used colors). This requires dedicated wall space and typically uses a combination of racks, shelving, and custom storage.
The key decision point is the 100-pot threshold. Below 100 pots, a single standard 120-slot rack suffices. At 100–150 pots, a painter should upgrade to a second rack or a larger wall system to avoid the overcrowding that forces pots into difficult-to-access positions. Beyond 150 pots, wall space becomes the limiting factor, not rack capacity.
CITADEL AND VALLEJO MIXED COLLECTIONS
A painter might own both Citadel and Vallejo paints due to project diversity (board games using Citadel, model kits using Vallejo), gift sets, or experimentation with competitor lines. Mixed collections present a storage challenge because Citadel pots are 32mm and Vallejo droppers are 26mm.
The incompatibility is absolute — a 26mm dropper cannot fit in a 33mm slot securely (it falls through), and a 32mm Citadel pot cannot fit in a 26mm slot (it jams). A painter with a substantial inventory of both must use separate racks.
If the painter’s collection is heavily weighted toward one brand — say, 120 Citadel pots and only 12 Army Painter washes (which are also 26mm) — the simplest solution is one main 33mm Citadel rack and one small 26mm secondary rack for the Army Painter washes. The overhead of maintaining two racks is minimal for small cross-brand collections.
If the painter’s collections are balanced — 80 Citadel, 80 Vallejo — two full-sized racks are necessary. This investment is justified by the visual clarity and workflow efficiency gained from segregation.
A modular wall system with mixed slot sections is another option. PROSCALE offers configurations with both 26mm and 33mm slot sections in the same installation, allowing a painter to integrate both brands into one wall system while maintaining segregation by slot size. This is the most visually unified approach and supports future growth in either direction.

OPERATIONAL SCENARIO
Marcus is a Warhammer 40K player who paints competitively. He invested in a full Citadel Base and Layer range over three years, reaching 130 pots organized by line in a custom wooden rack. When Games Workshop released Contrast paint, Marcus purchased a 30-pot starter set to experiment on a new army. He attempted to store the Contrast pots in his existing rack alongside his Base and Layer pots, in alphabetical order mixed throughout.
Within two weeks of active painting, Marcus had mixed up a Contrast Black Templar with a Base Black, applying semi-transparent black over highlight work and ruining three hours of detailed layering. He immediately segregated all Contrast pots to a dedicated wall shelf, marked each Contrast pot with a white paint marker on the lid, and never mixed them with his main rack again.
The lesson: Citadel Contrast paint’s behavioral difference demands storage segregation or explicit visual markers. A moment of careless reaching into a mixed rack can damage a model that took days to paint. Segregation or marking is cheap insurance.
FAQ
What rack size do I need for Citadel paints? Citadel pots are 32mm in diameter and require 33mm+ slot racks. A painter with 60–80 pots (typical hobby collection) needs a 120-slot 33mm rack. A painter with 150+ pots should split across two racks or use a modular wall system. Never use a 26mm rack designed for Vallejo or Army Painter — Citadel pots won’t fit.
Are Citadel paint pots all the same height? Citadel Base and Layer pots are both 18mm tall and fit identically in racks. Shade pots are slightly shorter (14mm), Dry pots are slightly shorter and stockier (15mm), and some Technical pots are taller (24ml). A well-designed 33mm rack with 20mm+ slot depth accommodates all standard Citadel lines without adjustment.
How do you organize Citadel paints by color? Most painters organize Citadel paints by line first (Base section, Layer section, Shade section) and then by color family within each line — reds together, skin tones together, metallics together. This hybrid approach supports both sequential painting (paint Base, then the corresponding Layer) and quick color-matching (find all red paints without scanning the entire collection).
Can you mix Contrast paint with Base paint in the same rack? While they fit in the same 33mm slots physically, Contrast and Base should be stored separately or clearly marked because mixing them during painting creates unpredictable results. Most painters either use a dedicated Contrast section or mark Contrast pots with a visible marker (white paint on the lid) to prevent accidental selection during active painting sessions.
What is the difference between Citadel Shade and Dry paints? Shade paints are washes designed to pool in recesses and create depth automatically; they’re fluid and flow into tight spaces. Dry paints are chalky, low-opacity, and designed for drybrushing; they’re extremely fragile and should be stored upright and undisturbed. Both fit 33mm racks but require different handling during storage and use.
Do you need a dedicated rack for Citadel if you only have 30 pots? No. A 60-slot 33mm rack holds 30 Citadel pots comfortably with room for growth. The primary decision is whether to segregate Citadel pots from Vallejo droppers. If your collection contains both, you need separate racks because the diameter mismatch is absolute. If your collection is Citadel-only, a single compact 33mm rack is sufficient.
For Citadel collections scaling beyond a single rack, a modular wall system with consistent 33mm slot sizing grows with your army. → View the full PROSCALE range →
