Grey Blue equivalents in other ranges
Several ranges orbit this color without landing on it. Here is the closest each brand manages, nearest first:
- Closest Humbrol equivalent: Humbrol Intermediate Blue, close enough that batch variation matters more (delta E 1.9).
- Best Green Stuff World option: Green Stuff World Smoked Blue, close, with a hint of drift side by side (delta E 2.3).
- From Monument Pro Acryl: Monument Pro Acryl Grey Blue, a near match with visible drift up close (delta E 4.0).
- The Two Thin Coats pick: Two Thin Coats Wolf Grey, a usable stand-in rather than a twin (delta E 4.4).
- Nearest in the Citadel catalog: Citadel Russ Grey, workable at tabletop distance, not up close (delta E 4.8).
- Best Tamiya option: Tamiya Field Blue, a usable stand-in rather than a twin (delta E 5.7).
Side by side the two agree in lightness and temperature; at delta E 1.9 the gap is smaller than the variation between two pots of the same paint.
