classColorOverSpeed

@codexo/exojs-particles / particles / stable

Per-frame, per-particle color sampler driven by velocity magnitude rather than lifetime ratio. Each live particle's tint is set to the gradient evaluated at `clamp((|velocity| - minSpeed) / (maxSpeed - minSpeed), 0, 1)`. Use cases: heat-mapping (slow=blue, fast=red), velocity-tinted trails, speed-gated highlights. GPU-eligible: gradient uploaded as a 256-tap 1D RGBA8 texture, sampled with linear filtering. Replaces the full color word — pair with a separate AlphaFadeOverLifetime after this module if you want to keep alpha controlled by lifetime.
