I know that the new background colours help some kind of colour blinds differentiate the colours easier, but I am also a colour blind (Deutan) and I can hardly tell the difference only if I look hard enough, even though I had no problem before.
I feel like it would be a lot better if there was a colour blind option that you could turn on and off.
As a fellow colorblind person, I’ve always had trouble with these colors. Thank you for saying something about it!
