Grey-Blue is a mid-tone muted blue with a cool undertone. For modelling, drop to Wwi French Artillery Grey in the recesses and step up to Raf Pru Blue Bs381C/636 on the edges, both AK Interactive paints. Substitutes are thinner on the ground; Two Thin Coats Shadow Blue is the nearest same-finish option at 92 percent, with 2 brands in strong-match range. A cross-brand swap will get you most of the way, but eyeball it against the original first.
Grey-Blue equivalents in other ranges
Several ranges orbit this color without landing on it. Here is the closest each brand manages, nearest first:
- Closest Two Thin Coats equivalent: Two Thin Coats Shadow Blue, close enough that batch variation matters more (delta E 1.5).
- Best Humbrol option: Humbrol Blue Grey, close, with a hint of drift side by side (delta E 3.5).
- From Tamiya: Tamiya Field Blue, workable at tabletop distance, not up close (delta E 4.4).
- Citadel's closest color: Citadel Russ Grey, a usable stand-in rather than a twin (delta E 5.6).
- Nearest in the Revell catalog: Revell Dark Grey (RAL 7011), workable at tabletop distance, not up close (delta E 6.7).
- Best Scale75 option: Scale75 Rogue Grey, a usable stand-in rather than a twin (delta E 7.0).
Side by side the two agree in lightness and temperature; at delta E 1.5 the gap is smaller than the variation between two pots of the same paint.
