Anyway, if you happened to peek at the illustration of the POC (used contrasting light / dark colours, plus patterns and softened letters of corresponding "inversion" [0]), do you think it is an improvement?
Author of the game also updated the contrast [1], so now it is light blue versus slightly darker violet, but still with same default (usually black) text colour [1]. Do you like it better? Or would you prefer classical black versus white or something in this lines?
Sure, and my response was to provide simple POC to try some alternative hopefully more accessible appearance on top of live version for folks with colour vision troubles and potentially for the author as well.

(It will break the moment author will change inline style.)
