Increase contrast between relearning and learning cards in graphs

image813×331 21.5 KB The new cards and re-learning cards are nearly the same color, and I really have to squint to tell the difference. In AnkiDroid, red was for forgotten cards and blue was for new cards. This was easy to read at a glance.

I agree. I'm having a much harder time parsing my Reviews graph on AnkiMobile (v. 25.09) now that Learning is orange and Relearning is red. The contrast of Learning as blue was fantastic.
