Petroleum Brown Wash is a very dark muted black with a neutral cast. Highlight it toward Transparent Green, the nearest lighter paint in the Monument Pro Acryl lane. Substitutes are thinner on the ground; Citadel Nuln Oil is the nearest same-finish option at 89 percent, with 1 brand in strong-match range. A cross-brand swap will get you most of the way, but eyeball it against the original first.
Petroleum Brown Wash equivalents in other ranges
Several ranges orbit this color without landing on it. Here is the closest each brand manages, nearest first:
- Closest Citadel equivalent: Citadel Nuln Oil, a near match with visible drift up close (delta E 2.3).
- Nearest in the The Army Painter catalog: The Army Painter Grim Black, close, with a hint of drift side by side (delta E 3.5).
- Best AK Interactive option: AK Interactive Smoke Black, workable at tabletop distance, not up close (delta E 6.7).
- From Humbrol: Humbrol Gloss Black, close, with a hint of drift side by side (delta E 2.5), but it is an opaque acrylic so treat it as a color reference, not a swap.
- Scale75's closest color: Scale75 Black, a near match with visible drift up close (delta E 2.6), but it is an opaque acrylic so treat it as a color reference, not a swap.
- Nearest in the P3 Paints catalog: P3 Paints Immortal Black, close, with a hint of drift side by side (delta E 3.4), but it is an opaque acrylic so treat it as a color reference, not a swap.
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 2.3 rather than an obvious shift.
