Flat Blue sits in the blue family: dark in tone, vivid in saturation, cool in cast. Substitutes are thinner on the ground; Humbrol Blue Angels Blue is the nearest same-finish option at 92 percent, with 1 brand in strong-match range. A cross-brand swap will get you most of the way, but eyeball it against the original first.
Flat Blue equivalents in other ranges
No brand clones Flat Blue outright, but 1 range comes close enough to swap. The best candidate from each catalog:
- Closest Humbrol equivalent: Humbrol Blue Angels Blue, close enough that batch variation matters more (delta E 1.6).
- Nearest in the Green Stuff World catalog: Green Stuff World Imperium Blue, a usable stand-in rather than a twin (delta E 4.2).
- Best AK Interactive option: AK Interactive Fluorescent Blue, workable at tabletop distance, not up close (delta E 5.2).
- From Monument Pro Acryl: Monument Pro Acryl Ultramarine, a usable stand-in rather than a twin (delta E 6.4).
- Revell's closest color: Revell Blue/Blau (RAL 5005), workable at tabletop distance, not up close (delta E 6.7).
- Nearest in the Scale75 catalog: Scale75 Sweet Dreams Blue, a usable stand-in rather than a twin (delta E 6.9).
The honest caveat: Humbrol Blue Angels Blue dries slightly cooler and more saturated than Flat Blue, so expect recess shading and edge highlights to shift with it.
