Field Blue is a dark muted blue with a cool undertone. It builds a smooth gradient with Medium Blue underneath and JN Grey on the highlights, all in the Tamiya line.

A cross-brand swap will get you most of the way, but eyeball it against the original first.
Field Blue equivalents in other ranges
Several ranges orbit this color without landing on it. Here is the closest each brand manages, nearest first:
- Closest AK Interactive equivalent: AK Interactive Ocean Gray (Fs 35164), close enough that batch variation matters more (delta E 1.8).
- Citadel's closest color: Citadel The Fang, close, with a hint of drift side by side (delta E 4.0).
- Nearest in the Green Stuff World catalog: Green Stuff World Smoked Blue, workable at tabletop distance, not up close (delta E 4.3).
- Best Humbrol option: Humbrol RAF Blue, a usable stand-in rather than a twin (delta E 4.9).
- From Two Thin Coats: Two Thin Coats Shadow Blue, workable at tabletop distance, not up close (delta E 5.5).
- Vallejo's closest color: Vallejo Grey Blue, a usable stand-in rather than a twin (delta E 5.7).
Side by side the two agree in lightness and temperature; at delta E 1.8 the gap is smaller than the variation between two pots of the same paint.
