Description
Returns the smallest channel value among R, G, B, and A in the given linear color.
Caveats & Gotchas
- • Alpha is included in the search — a fully transparent color (alpha=0) will always return 0 regardless of the RGB values, which can mask low-saturation detection.
- • For colors with negative channel values (valid in HDR pipelines), the result can be negative.

if (MinChannel < 0.2f)
{
// At least one channel is very dark
