Medium Blue equivalents in other ranges
1 of the 9 brands with a mapped match get genuinely close to Tamiya Medium Blue, though none is a clone. Brand by brand, the nearest colors are:
- Closest Monument Pro Acryl equivalent: Monument Pro Acryl Faded Ultramarine, close enough that batch variation matters more (delta E 1.5).
- The Army Painter's closest color: The Army Painter Stratos Blue, close, with a hint of drift side by side (delta E 3.3).
- Nearest in the Citadel catalog: Citadel Alaitoc Blue, a near match with visible drift up close (delta E 3.7).
- Best Vallejo option: Vallejo Elfic Blue, a usable stand-in rather than a twin (delta E 4.1).
- From Two Thin Coats: Two Thin Coats Eldar Robe, workable at tabletop distance, not up close (delta E 4.1).
- Scale75's closest color: Scale75 Mediterranean Blue, a usable stand-in rather than a twin (delta E 4.2).
The honest caveat: Monument Pro Acryl Faded Ultramarine dries slightly cooler and more saturated than Medium Blue, so expect recess shading and edge highlights to shift with it.
