Sea Grey

1 of the 10 brands with a mapped match get genuinely close to Humbrol Sea Grey, though none is a clone. Brand by brand, the nearest colors are:

• Closest AK Interactive equivalent: AK Interactive A-14 Interior Steel Grey, close, with a hint of drift side by side (delta E 2.4).
• Nearest in the Tamiya catalog: Tamiya Sea Grey 2, a near match with visible drift up close (delta E 2.6).
• Best Revell option: Revell Mouse grey/Mausgrau (RAL 7005), a usable stand-in rather than a twin (delta E 4.7).
• From The Army Painter: The Army Painter Uniform Grey, workable at tabletop distance, not up close (delta E 5.2).
• The Two Thin Coats pick: Two Thin Coats Shadow Blue, a usable stand-in rather than a twin (delta E 5.7).
• Nearest in the Citadel catalog: Citadel Air Caste Thinner, workable at tabletop distance, not up close (delta E 5.9).

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 2.4 rather than an obvious shift.
