Relic Blue is a mid-tone vivid blue with a cool undertone. For modelling, drop to Witching Hour Blue in the recesses and step up to Celestial Blue on the edges, both Two Thin Coats paints. Relic Blue is a little less common: the closest same-finish match, Vallejo Fluorescent Blue, reaches 88 percent, and 2 other brands carry a strong same-finish alternative. A cross-brand swap will get you most of the way, but eyeball it against the original first.
Relic Blue equivalents in other ranges
No brand clones Relic Blue outright, but 1 range comes close enough to swap. The best candidate from each catalog:
- Closest Vallejo equivalent: Vallejo Fluorescent Blue, a near match with visible drift up close (delta E 2.3).
- From Citadel: Citadel Calth Blue Clear, close, with a hint of drift side by side (delta E 3.3).
- The Army Painter's closest color: The Army Painter Crystal Blue, workable at tabletop distance, not up close (delta E 4.2).
- Nearest in the Scale75 catalog: Scale75 Sky Blue, a usable stand-in rather than a twin (delta E 5.1).
- Best Humbrol option: Humbrol Mediterranean Blue, workable at tabletop distance, not up close (delta E 6.0).
- From Monument Pro Acryl: Monument Pro Acryl Sky Blue, a usable stand-in rather than a twin (delta E 6.0).
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.
