Grey Knights Steel equivalents, brand by brand
Several ranges orbit this color without landing on it. Here is the closest each brand manages, nearest first:
- Closest Vallejo equivalent: Vallejo Steel Grey, a swap nobody spots at arm's length (delta E 1.7).
- Best P3 Paints option: P3 Paints Cold Steel, a near match with visible drift up close (delta E 3.3).
- From Humbrol: Humbrol Gunmetal, a usable stand-in rather than a twin (delta E 5.0).
- Tamiya's closest color: Tamiya Gun Metal, workable at tabletop distance, not up close (delta E 5.8).
- Nearest in the The Army Painter catalog: The Army Painter Gun Metal, only a loose relative (delta E 8.7).
- Best Two Thin Coats option: Two Thin Coats Sir Coates Silver, only a loose relative (delta E 9.0).
We checked the Lab numbers for a hidden catch and there is none: lightness and temperature both line up, so this swap is as safe as they come.

Frequently asked
What is the closest equivalent to Citadel Grey Knights Steel?
The closest same-finish match is Vallejo Steel Grey at 92% color similarity.
What finish is Grey Knights Steel?
Grey Knights Steel is a metallic paint with a silver tone and a reflective finish. Because the shine comes from metal flake, a flat paint can match the color and still be wrong for the job, which is why cross-finish matches here are references rather than swaps.
What do I highlight and shade Grey Knights Steel with?
Highlight Grey Knights Steel toward Runefang Steel and shade it down into Iron Hands Steel, both Citadel paints in the same finish family.
