Ultramar Blue equivalents and near misses
Fair warning: nothing matches Green Stuff World Ultramar Blue cleanly. The options below are the least bad, and every one of them drifts.
Closest Tamiya equivalent: Tamiya JNSDF Blue, close, with a hint of drift side by side (delta E 2.5).
AK Interactive's closest color: AK Interactive Imperial Blue, a near match with visible drift up close (delta E 3.0).
Nearest in the Vallejo catalog: Vallejo Dark Blue, close, with a hint of drift side by side (delta E 3.5).
Best Revell option: Revell Night blue/Nachtblau (RAL 5022), workable at tabletop distance, not up close (delta E 4.0).
Check it on a spare model first, because Tamiya JNSDF Blue sits slightly cooler than the original and the difference grows over large flat panels.
