Color-wise this is a muted, light teal leaning cool. Within the Two Thin Coats range it ladders cleanly, Kobold Grey for the shadows and Ray Gun Glow for the highlights. Substitutes are thinner on the ground; AK Interactive Rlm 78 (1941) 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.
Frost Blue equivalents, brand by brand
No brand clones Frost Blue outright, but 1 range comes close enough to swap. The best candidate from each catalog:
- Closest AK Interactive equivalent: AK Interactive Rlm 78 (1941), close, with a hint of drift side by side (delta E 2.3).
- The P3 Paints pick: P3 Paints Voltaic Blue, workable at tabletop distance, not up close (delta E 4.8).
- Nearest in the Citadel catalog: Citadel Celestra Grey, a usable stand-in rather than a twin (delta E 5.5).
- Best Vallejo option: Vallejo Pale Blue, workable at tabletop distance, not up close (delta E 5.6).
- From Humbrol: Humbrol Grey, a usable stand-in rather than a twin (delta E 6.3).
- Tamiya's closest color: Tamiya Medium Sea Grey 2, workable at tabletop distance, not up close (delta E 7.1).
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.
