I'm afraid a lot of times it would hard to read as everyone uses different themes on d2jsp.
Sorry, but I don't think this would be useful or cool.

Basically my thoughts on the matter. Some people are on dark themes when they use certain text colors, but that text color is honestly hardly visible on some other styles. And for a lot of colored posts, I find myself highlighting the posts in order to read them. It's honestly not much of a hinderance, but I don't want to/shouldn't be highlighting every other post regardless.

Voted no.
