Painting Multiple Armies: How to Organize Paints Across Different Warhammer Projects
When you paint multiple Warhammer armies — Space Marines, Orks, Necrons, and a side project in Age of Sigmar — separating paints by project breaks down fast. A master collection organized by color family solves this once you own 80+ paints, because Agrax Earthshade and Leadbelcher are needed across all four armies.
THE PROBLEM: MULTI-ARMY PAINT FRAGMENTATION
Most painters start with one project. You buy a starter paint set. You organize it in a small rack or drawer using PROSCALE modular paint racks or similar storage. The system works because every paint in that set belongs to the same army. Then you start a second army. You buy a second set of paints. You either create a second small rack — or you dump the new paints into the old one and lose any organizational logic at all.
By the third army, the problem compounds. You now own paints from multiple manufacturers. Citadel and Vallejo bottles are different sizes and need different storage (detailed in the comprehensive Citadel storage guide and Vallejo storage guide). You’re cycling through four or five concurrent projects, each requiring access to a different subset of 20–40 colors. Some colors repeat across armies — Nuln Oil works for all factions. Others are faction-specific — Ork Green is only for Orks.
This is where project-based organization fails. Separating paints into three project trays — one for Death Guard, one for Necrons, one for Stormcast — means buying 15 bottles of Agrax Earthshade across three boxes. It means spending five minutes each session hunting for the one bottle of Nuln Oil, which is currently in the Necrons tray but you’re painting Death Guard today.
A master collection solves this. Everything lives in one organized system. You pull from that system based on what you’re painting in the current session. At 80+ paints, a master collection is more efficient than separate project boxes.
ORGANIZATION STRATEGY: PROJECT-BASED VS MASTER COLLECTION
The question isn’t “project-based or master?” It’s “when does the breakover happen?” There are three organizational approaches, each suited to a different scale of collection.
Master collection: a single organized system holding all paints across all projects, grouped by color family (reds, greens, blues, metallics, etc.) rather than by army faction. This approach works when 10–15% of your paints are shared between multiple armies.
PROJECT-BASED ORGANIZATION (Best for: Under 60 paints)
You own one or two complete sets. Space Marines requires 35 Citadel pots. You add an Ork army, which requires another 35. You create two separate paint trays or racks. Each project is self-contained. When you’re painting Space Marines, only Space Marine colors are visible. No cognitive overhead. No hunting.
This approach works until you own a third army or until color overlap becomes unavoidable. Agrax Earthshade belongs in all three trays. You either buy three bottles or shuffle one between boxes every session. Once the friction reaches that level, switch to a master collection.
MASTER COLLECTION ORGANIZED BY COLOR FAMILY (Best for: 80–200+ paints)
All paints live in one system, organized by color family — reds, blues, yellows, greens, browns, metallics, special effects. Within each color family, group by brand (Citadel reds in one area, Vallejo reds in another). This works because most painters need to select from the same core color families regardless of which army they’re painting.
A painter with Death Guard, Necrons, and Stormcast Eternals needs blacks, metallics, greens (for slime and technical effects), and golds/silvers. A master collection by color family makes those visible at once. You don’t think “which army am I painting?” — you think “what color am I using?” and reach for that section.
The overhead: organizing and maintaining the system takes time upfront. But every painting session afterward is faster.
HYBRID: MASTER COLLECTION WITH “ACTIVE PROJECT” SHELF (Best for: 100–300+ paints and regular project rotation)
You keep a master collection organized by color family in permanent wall storage. You maintain a secondary “active project” shelf or small rack for the 15–25 colors you’re currently using most. When you finish a project phase, you return unused paints to the master collection and refill the active shelf with paints for the next project.
This combines the visual organization benefit of a master collection with the quick-access advantage of a project-specific setup. The active shelf acts as a “session workspace.” The master collection is your library.
| Organization Method | Best for | Setup time | Session friction | Storage density |
|---|---|---|---|---|
| Project-based trays | 1–2 projects, under 60 paints | <1 hour | Low (if well organized) | Moderate |
| Master by color family | 3+ projects, 80–200 paints | 2–4 hours | Low (visual scanning) | High |
| Hybrid (master + active shelf) | 4+ projects, 100–300+ paints | 4–6 hours | Very low (active shelf only) | Very high |
WHEN COLOR OVERLAP BECOMES UNAVOIDABLE
Active project shelf: a small 15–25 slot secondary storage unit holding the colors you’re actively using in a current painting session, pulled from a larger master collection. The active shelf stays on your desk; the master collection stays on a wall or permanent storage, creating a two-tier system that eliminates session friction.
The breakover point happens when the same paint appears in multiple project setups. That paint is the friction point.
Agrax Earthshade is the universal test. This brown wash/shade works on virtually every Citadel-painted army. Space Marines, Orks, Necrons, Deathwing Dark Angels, Stormcast Eternals — all use it. If you paint across three armies and own only one bottle of Agrax Earthshade, that bottle shuffles between project trays daily.
At that moment, project-based organization has become more work than a single master collection. The time cost of finding and moving shared paints exceeds the cognitive load of searching a larger, organized system.
Leadbelcher and other metallics follow the same pattern. Nearly every Warhammer army uses at least three metallic colors. Separate project boxes mean buying paints multiple times. A master collection means one bottle, one location.
This is the practical threshold: count how many paints appear in multiple armies. Once that number reaches 10–15 paints (10–15% of your collection), migrate to a master collection.
SCENARIO: THE MULTI-ARMY REORGANIZATION
The painter: Alex owns 180 Citadel paints across Death Guard, Necrons, and Stormcast Eternals, plus Ultramarines as a secondary army. He kept them in three project trays — one per faction. Each tray held 45–60 paints. For the first year, this worked. Each project was self-contained.
Then he started painting all three armies in the same month (pandemic hobby surge). Suddenly, every painting session involved moving trays. Agrax Earthshade, Nuln Oil, all three metallics, and the technical paints lived in all three trays. He was cycling them between boxes constantly.
Session friction became unbearable around session eight. He was spending 4–5 minutes per session just managing which paints were in which tray.
The decision: Alex converted to a master collection organized by color family — reds, oranges, yellows, greens, browns, metals, skin tones, special effects. He organized it in a 3-shelf wall system using PROSCALE modular paint racks with 32mm Citadel pot compatibility.
Shelf one: Reds, oranges, yellows (60 pots). Shelf two: Greens, browns, blacks, skin tones (70 pots). Shelf three: Metallics, whites, special effects (50 pots).
The outcome: His next session painting Death Guard took 12 minutes total (previously 17 minutes with tray shuffling). He wasn’t hunting for colors anymore — browns and blacks were on shelf two, metallics on shelf three. The cognitive load dropped because he wasn’t mentally sorting “which project am I in?” anymore. He was sorting “what color do I need?”
Session efficiency improved across all three armies. The wall system took up more physical space than three trays. But the payoff was consistency: every painting session started the same way — glance at the wall, pull the colors needed, paint.
COLOR OVERLAP ANALYSIS: BUILDING YOUR MASTER STRUCTURE
Not all armies share the same color palette. But most share the core anchors. Build your master collection around these:
Universal colors across Warhammer armies:
- Nuln Oil (dark shade — works everywhere)
- Agrax Earthshade (brown wash — every army needs earth tones)
- Leadbelcher (metallic base — almost universal)
- Retributor Armor (gold — most armies have gold)
- Ironbreaker (silver — most armies have silver)
- Black (base coat for many armies)
- White (skull-and-robe details)
- Rhinox Hide or Mournfang Brown (for brown basing)
Faction-specific colors:
- Space Marines: Ultramarine Blue, Imperial Blue, Caledor Sky, whites for trim
- Orks: Waaagh! Green, Goblin Green, yellows for detail
- Necrons: Leadbelcher, Ironbreaker (metallics dominate), Nuln Oil for depth
- Stormcast: Stormhost Silver (alternative metallics), golds, blues for detail
Paint your collection by counting faction-specific colors. In this example, only 8 colors are truly faction-specific (one blue for Marines, two greens for Orks, one silver variant for Stormcast, three golds). The other 172 paints are shared workhorses or faction-adjacent (browns, blacks, metallics, skin tones, special effects).
Organize around the 172 shared paints. Store faction-specific colors in a secondary section or label them clearly within the master collection. This way, 95% of your collection is immediately useful across all projects.
ACTIVE PROJECT SHELF: THE SESSION-LEVEL LAYER
If you’re rotating between projects weekly or painting multiple armies simultaneously, add an intermediate layer: an active project shelf.
This is a small 15–25 slot rack dedicated to your current painting session, aligned with the batch painting desk efficiency principles for session-level organization. Before you start painting Death Guard, you pull the core Death Guard colors from the master collection into the active shelf: Mournfang Brown, Castellan Green, Verminlord Hide (greens), Agrax Earthshade, Nuln Oil, Leadbelcher, Ironbreaker, and three metallic variants. That’s 12 colors within arm’s reach. The master collection stays on the wall or in a larger storage unit.
The mechanical benefit: you’re not physically moving large storage every session. You’re just swapping a small active shelf. That takes under two minutes. The visual benefit: your working area stays clear. You see only the colors relevant to the current painting task.
When you finish Death Guard for the week and switch to Stormcast, you return the Death Guard colors to the master collection and load the Stormcast colors into the active shelf. The physical boundary between “library” (master collection) and “workspace” (active shelf) eliminates cognitive load.
FAQ
Q: How many paints should I own before switching to a master collection?
A: 80–100 paints is the practical threshold. Below that, project-based organization is faster. Above it, the shared paints (Agrax Earthshade, metallics, special effects) become friction points. The real signal is when the same paint appears in three or more project boxes — that’s when you reorganize.
Q: Can I use both a master collection and project trays at the same time?
A: Yes, and it’s called a hybrid setup. Keep a permanent master collection on a wall system, and maintain a small “active project” tray for colors you use this week. Most multi-army painters adopt this by accident — they keep a master wall collection and a small tray on the desk. Formalizing it as a strategy reduces friction.
Q: What if I paint GW, Vallejo, and Army Painter paints in the same session?
A: Organize by color family first, then by brand within that family. All reds together, subdivided into Citadel reds, Vallejo reds, and Army Painter reds. This works because you’re selecting by color need, not brand loyalty. When you need “a dark brown wash,” you scan the brown section — you don’t hunt across three different storage systems.
Q: Should I organize by project first, then by color, or by color first, then by project?
A: Color first always. Once you own 80+ paints across 3+ armies, organizing by project is backward. You’ll be looking for “a metallic gold” or “a dark shade” more often than you’ll be thinking “I’m painting Stormcast today.” Master collections organized by color family align with how your brain actually selects paints mid-session.
Q: What if I finish an army and sell it — do I reorganize again?
A: Only if you remove a large faction-specific block of paints. If you sell your Orks (which owns 15 faction-specific greens and yellows), you remove those colors from the active project shelf or the faction-specific secondary section — but the master collection stays intact. Most paints you used for Orks (metallics, browns, blacks, shades) are useful for other armies.
Q: How do I prevent paint loss when I switch between multiple projects?
A: Accountability through visibility. In a project tray, you can lose a bottle to a shelf corner for months. In a master collection organized by color family, every bottle is visible and in one place. If Nuln Oil is supposed to be in the brown section and it’s not there, you know it’s with the active project shelf. The system creates accountability through structure, not through manual checking.
If your collection has outgrown a single shelf and you’re managing paints across multiple concurrent armies, a master collection organized by color family eliminates the session friction of moving paint between project boxes. Start by listing which paints appear in three or more army projects — those are your signal to consolidate. For a wall-mounted master collection that scales from 80 to 300+ paints, modular racks designed for Citadel pot compatibility offer the flexibility to add shelves as your collection grows.
