Color-wise this is a muted, dark metallic silver leaning cool. For modelling, drop to Iron Hands Steel in the recesses and step up to Runefang Steel on the edges, both Citadel paints. This color is somewhat distinctive: 2 brands offer a strong same-finish match, Vallejo Steel Grey closest at 92 percent. Expect a close but not identical result from a swap, so check it on the model before committing a whole unit.

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.
