In the newest production homepage, the green progress partial-bars under items are very difficult for me to distinguish from the grey unfinished-progress partial-bars. I have to mouse-over to see where I really am.
Making the grey lighter is one possible change that would help me quite a lot.
I’ve seen other discussions of the pinks/purples for the various progress levels. All of those colors are quite distinct for me and are working just fine.
Thanks for continuing to improve WaniKani!
