It would be nice if they not only added more dyes but also overhauled all the colors and enhanced them. Some colors just look absolutely awful, and some colors are just barely lighter or darker then another and I genuinely cannot tell the difference between them unless I look really closely at them. Since they did 2 dye slots maybe it's possible someday we'll get an actual dye update, but given some of the absolutely BAFFLING decisions for what they decided was "good" to actually dye for some of these two-dye slot items, I won't hold my breath for anything.
