In the pot, Petrol Blue reads as a cool teal, dark and moderate. Within the Humbrol range it ladders cleanly, Matt Tank Grey for the shadows and Matt Olive Drab for the highlights. This color is somewhat distinctive: 2 brands offer a strong same-finish match, Monument Pro Acryl Dark Turquoise closest at 82 percent. Any substitute is a mixing base rather than a drop-in, so tune it on the model.
Petrol Blue equivalents and near misses
Fair warning: nothing matches Humbrol Petrol Blue cleanly. The options below are the least bad, and every one of them drifts.
Closest Monument Pro Acryl equivalent: Monument Pro Acryl Dark Turquoise, close, with a hint of drift side by side (delta E 3.6).
From The Army Painter: The Army Painter Deep Azure, a near match with visible drift up close (delta E 3.7).
Scale75's closest color: Scale75 Ego Green, a usable stand-in rather than a twin (delta E 4.5).
Nearest in the Citadel catalog: Citadel Sons of Horus Green, workable at tabletop distance, not up close (delta E 4.9).
Check it on a spare model first, because Monument Pro Acryl Dark Turquoise sits slightly cooler and more saturated than the original and the difference grows over large flat panels.
