There is other, more sinister way to fuck it up, by just loading "wrong" color keys from the theme that still sorta look okay on white theme but are unreadable.

There is other, more sinister way to fuck it up, by just loading "wrong" color keys from the theme that still sorta look okay on white theme but are unreadable. Basically, instead of reading description and using a color key from theme as designed, someone uses "default" (or whatever they have currently set on machine) color theme as essentially palette to paint their app with, disregarding original purpose and end up broken with some themes.
