I've tried to run this mod several times and, while I would really like to stop some of my guys making extra meals when what I really need is beer (or vice versa), I inevitably I find myself uninstalling purely due to poor readability making the setting\changing of priorities a chore (more so than usual).

Vanilla Rimworld priorities are coloured so that, each priority stands out compared to the others by both number(shape) and colour which allows each to stand out when in a large group.
For comparison in worktab all colours are green->grey meaning when looking for a 2 vs a 3, there is effectively no colour difference and the increased number of possible priorities makes the screen just a mess of numbers.

I attempted to fix this by installing PriorityMaster, which gives the option to manually change the colour of each priority, but it seems that WorkTab overwrites whatever changes i set via that mod and there dont seem to be any alternatives to either mod (PriorityMaster allows adding more numbers for priorities, but not change sub task priorities)

Allowing custom in game setting of colours (via mod settings) would dramatically fix this problem, and (compared with setting preset colour options) would allow the user to account for colour blindness or preference.

For reference what I'd be personally doing is setting 1 to blue, then 2+3 green\darkgreen, 4+5 yellow\darker yellow, 6+7 brown\dark brown, and 8+9 grey\white, effectively making sets of high\low priority groupings where a low priority sub task could be the same colour but different shade that its main task priority, while main tasks conform to the original green-yellow-brown-grey colour order and yet all being perfectly readable, but i get that this is a truly personal.issue that many probably won't want

If this is not possible for some reason, allowing PriorityMaster colour selection to take priority would allow this functionality by default (presumably by preventing overriding\applying of colour settings if PriorityMaster is detected?).
