as someone whos tried getting a good blue hair color multiple times and failed, ive been wondering, the character hair colors arent bound to swatches the same way equipment color swatches are (dye pots and all that) and come up solely from within the character edit menu

is there any reason the hair menu couldnt be changed in a qol patch from a static swatch system (which is already an rgb value just limited to specific values) to either an rgb slider system, or a hue/saturation/luminosity slider set for greater player customization?
