Near-Black + Acid Accent Is a Default
SHOULD: Treat near-black + one bright acid-green/vermilion accent as a reflex, not a choice — it is one of the looks AI-generated design clusters around, and its tell is interchangeability: the same surface and accent look equally plausible on a fintech dashboard, a wellness app and a dev tool, which means it was derived from none of them. Derive the dark surface instead: take the product's own hue, hold the hue angle and drop chroma, and pull the accent from the subject's material world rather than a neon swatch. (Distinct from `design-impeccable-dark-glow`, which is about glow SHADOWS, not the palette.)
The dark canvas with one bright acid-green or vermilion accent arrives regardless of subject — derive the dark surface instead

Why it matters
Look (2) is the "technical, serious, a bit dangerous" reflex, and its tell is interchangeability: paste the same near-black surface and the same acid-green accent onto a fintech dashboard, a wellness app, and a dev tool, and all three still look plausible — which is precisely the problem, because a palette that fits every subject was derived from none of them.
Distinct from `design-impeccable-dark-glow`, which is about glow SHADOWS on dark surfaces, not the palette itself. The fix is derivation: take the product's own hue, hold the hue angle and drop chroma for the surface (see `design-impeccable-tinted-neutrals`), and pull the accent from the subject's material world rather than from a neon swatch.
