An alternative idea to hexadecimals: color coded numbers - for instance, white 00-99 is 00-99, red 00-99 is 100-199, blue 00-99 is 200-299, and so on. No need to translate any hexadecimals to binary, just know what color pertains to what number set. And it would greatly increase resolution past 255.
I’m still very new to tracking, but this seems to be feasible. Maybe follow ROYGBIV, or whatever color scheme the user prefers.
This is no feature request of course, but maybe far down the line as an alternative. Or in some new tracker. Am I missing something, or would this work?
