Color-wise this is a muted, light blue leaning cool. Within the Tamiya range it ladders cleanly, Light Blue for the shadows and Sky Grey for the highlights. Substitutes are thinner on the ground; Humbrol Azure Blue is the nearest same-finish option at 80 percent, with 1 brand in strong-match range. Any substitute is a mixing base rather than a drop-in, so tune it on the model.
Royal Light Blue equivalents and near misses
Fair warning: nothing matches Tamiya Royal Light Blue cleanly. The options below are the least bad, and every one of them drifts.
Closest Humbrol equivalent: Humbrol Azure Blue, a usable stand-in rather than a twin (delta E 4.0).
From Citadel: Citadel Fenrisian Grey, workable at tabletop distance, not up close (delta E 4.1).
AK Interactive's closest color: AK Interactive Raf Azure Blue, a usable stand-in rather than a twin (delta E 4.5).
Nearest in the Revell catalog: Revell Grey/Grau (RAL 7001), workable at tabletop distance, not up close (delta E 4.9).
The honest caveat: Humbrol Azure Blue dries slightly darker than Royal Light Blue, so expect recess shading and edge highlights to shift with it.
