Sure. Fancy methods to darken and lighten a color with the correct gamma adjustment would be nice for simple use cases.
However, Roblox should not spend 4 years designing this magical API that satisfies everyone before doing the bare minimum for a simple datatype that should just be an extension of Vector3 behind the scenes anyway.
Currently, to write your own algorithms involving color transformations or moving between color spaces, you’re better off just using a Vector3 as an intermediary, or working with the RGB components as separate variables and duplicating math across all of them manually. Like a caveman.
If I recall, Vector3s have some optimization behind the scenes for mathematical operations. Where does that leave this classic gist standing in terms of performance? CIELUV Interpolator
