Signal Red is a mid-tone vivid red with a warm undertone. Matching it is straightforward: Revell Luminous Red/Leuchtrot lands at 85 percent in the same finish, and 3 brands in all carry a close same-finish swap. Highlight it toward Blaze Gloss, the nearest lighter paint in the Humbrol lane. Treat it as an easy swap, just confirm the finish type matches before you commit.
Signal Red equivalents in other ranges
Signal Red is awkward to replace. Treat the matches below as starting points for a mix rather than straight swaps.
Closest Revell equivalent: Revell Luminous Red/Leuchtrot, a near match with visible drift up close (delta E 3.1).
Nearest in the Citadel catalog: Citadel Jokaero Orange, close, with a hint of drift side by side (delta E 3.2).
Best Green Stuff World option: Green Stuff World Red Truth, a near match with visible drift up close (delta E 3.3).
From Vallejo: Vallejo Fluorescent Orange, a usable stand-in rather than a twin (delta E 4.4).
The honest caveat: Revell Luminous Red/Leuchtrot dries clearly cooler and more muted than Signal Red, so expect recess shading and edge highlights to shift with it.
