Lemmy’s default theme performs well in black-and-white but it’s difficult to figure out if I already upvoted something. The arrows in the upvote and downvote buttons change shades after selecting them but the difference is practically imperceptible.
I’m hoping that upvote and downvote buttons could be made more accessible to color-blind users. Here’s a very rough sketch of a possible solution where the whole button element changes color:

I would deeply appreciate an improvement to this issue. Thanks for keeping Lemmy accessible.
