Color-wise this is a muted, light grey leaning neutral. No shortage of substitutes here, Concrete from Humbrol matches at 94 percent and 4 brands carry a strong same-finish near-match. It builds a smooth gradient with Desert Tan underneath and Pale Grey Blue on the highlights, all in the Vallejo line. In practice you can substitute across brands here without anyone noticing at arm's length.
Sky Grey equivalents, brand by brand
3 of the 11 brands with a mapped match get genuinely close to Vallejo Sky Grey, though none is a clone. Brand by brand, the nearest colors are:
- Closest Humbrol equivalent: Humbrol Concrete, a swap nobody spots at arm's length (delta E 1.3).
- Nearest in the Monument Pro Acryl catalog: Monument Pro Acryl Bright Neutral Grey, close enough that batch variation matters more (delta E 1.6).
- Best Citadel option: Citadel Grey Seer, close, with a hint of drift side by side (delta E 2.1).
- From AK Interactive: AK Interactive Raf Sky Grey, a near match with visible drift up close (delta E 3.3).
- Tamiya's closest color: Tamiya Light Sea Grey, a usable stand-in rather than a twin (delta E 4.1).
- Nearest in the P3 Paints catalog: P3 Paints Retribution White, workable at tabletop distance, not up close (delta E 5.0).
We checked the Lab numbers for a hidden catch and there is none: lightness and temperature both line up, so this swap is as safe as they come.
