What problem does this solve or what need does it fill?

Colors are difficult to read. For example, it's hard to tell that Color::rgb(0.8, 0.3, 0.7) is pink.

Describe the solution would you like?

Add a LCH color function as well as the HEX colors. The LCH color space allows for colors that are somewhat related to how people actually see it.

Describe the alternative(s) you've considered?

N/A
