-ColorAide has developed an experimental chroma reduction technique that employs ray tracing. Its aim is to provide
-faster chrome reduction for gamut mapping using constant lightness. This approach specifically targets RGB gamuts, or
-spaces that can be represented with RGB gamuts. Additionally, if ColorAide can detect a linear version of the targeted
-RGB gamut, that version will be used automatically for best results. Currently ColorAide can gamut map all officially
-supported color spaces as they either have an RGB gamut or can be coerced into one.

 The ray trace approach works by taking a given color and converting it to a perceptual Lab-ish or LCh-ish color space
 (the default being OkLCh) and then calculates the achromatic version of the color (chroma set to zero). Assuming the
