Fine, i'll do it myself. This is a Scratch project that can turn OKLAB values into Scratch's scuffed approximation of HSV. Due to Scratch not actually using proper HSV, aswell as some OKLAB colors being outside the sRGB color space, this is an approximation of the real deal. Feel free to use for any projects!
Wikipedia page i used: https://en.wikipedia.org/wiki/Oklab_color_space OKLAB was invented by the man the myth the legend Björn Ottosson, whom I will forever be praising. I couldn't find any other projects about this topic, so I guess i'm the first. If I missed any though, credits to them I guess.
