In the pot, Rlm 78 (1941) reads as a cool blue, light and muted. For modelling, drop to Blue Fs 35190 in the recesses and step up to Rlm 78 (1942) on the edges, both AK Interactive paints. Substitutes are thinner on the ground; Two Thin Coats Frost Blue is the nearest same-finish option at 89 percent, with 1 brand in strong-match range. Expect a close but not identical result from a swap, so check it on the model before committing a whole unit.
Rlm 78 (1941) equivalents, brand by brand
No brand clones Rlm 78 (1941) outright, but 1 range comes close enough to swap. The best candidate from each catalog:
- Closest Two Thin Coats equivalent: Two Thin Coats Frost Blue, close, with a hint of drift side by side (delta E 2.3).
- Nearest in the Vallejo catalog: Vallejo Pale Blue, workable at tabletop distance, not up close (delta E 4.3).
- Best Humbrol option: Humbrol Grey, a usable stand-in rather than a twin (delta E 4.5).
- From P3 Paints: P3 Paints Underbelly Blue, workable at tabletop distance, not up close (delta E 4.7).
- Citadel's closest color: Citadel Celestra Grey, a usable stand-in rather than a twin (delta E 5.5).
- Nearest in the Revell catalog: Revell Grey / Grau (RAL 7001), workable at tabletop distance, not up close (delta E 5.7).
The drift here is spread thinly across hue, lightness and saturation rather than leaning one way, so the mismatch reads as a general haze at delta E 2.3 rather than an obvious shift.
