Color-wise this is a muted, mid-tone grey leaning neutral. No shortage of substitutes here, Medium Sea Grey from Humbrol matches at 85 percent and 4 brands carry a strong same-finish near-match. Within the AK Interactive range it ladders cleanly, English Grey for the shadows and M-485 Blue-Grey for the highlights. Bottom line: run out mid-project and another brand will get you within a shade.
Grey Blue equivalents and near misses
Fair warning: nothing matches AK Interactive Grey Blue cleanly. The options below are the least bad, and every one of them drifts.
Closest Humbrol equivalent: Humbrol Medium Sea Grey, close, with a hint of drift side by side (delta E 3.0).
Best Revell option: Revell Mouse grey/Mausgrau (RAL 7005), a near match with visible drift up close (delta E 3.5).
From Tamiya: Tamiya Medium Grey, a usable stand-in rather than a twin (delta E 4.0).
Scale75's closest color: Scale75 Graphite, workable at tabletop distance, not up close (delta E 4.5).
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 3.0 rather than an obvious shift.
