Rated 3 out of 5 stars

Сравнив с Color Transform 4.1 от pjs и Blank Your Monitor + Easy Reading 1.9.7 от dlento предпочел последний.

This review is for a previous version of the add-on (5.4). 

Since BYM simply sets the default color options, it completely wipes out functional differences between text colors and it may lead to unreadable text on top of background images.
