Dark Sea Blue equivalents, brand by brand
2 of the 11 brands with a mapped match get genuinely close to Vallejo Dark Sea Blue, though none is a clone. Brand by brand, the nearest colors are:
- Closest Green Stuff World equivalent: Green Stuff World Steel Grey, close, with a hint of drift side by side (delta E 2.2).
- AK Interactive's closest color: AK Interactive Oxford, a near match with visible drift up close (delta E 2.2).
- Nearest in the Monument Pro Acryl catalog: Monument Pro Acryl Payne's Grey, close, with a hint of drift side by side (delta E 2.5).
- Best Scale75 option: Scale75 Siesta Blue, a near match with visible drift up close (delta E 3.9).
- From Revell: Revell Anthracite/Anthrazit (RAL 7021), a usable stand-in rather than a twin (delta E 4.5).
- Humbrol's closest color: Humbrol Matt Navy Blue, workable at tabletop distance, not up close (delta E 5.5).
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 2.2 rather than an obvious shift.
