sangheeta Yea the problem with that is there isn't any one single good solution besides disabling their custom colors they have on hover.
For your own profile, it will be grey. For others it is the primary color found in your avatar it seems, which can vary. I can see about forcing a specific background color but it may not apply depending on how they're doing the styling (my guess is inline style attribute setting).
I do agree that readability of that is difficult, so it'll be something I'll see about correcting when I'm available to do so. I appreciate the feedback on it ❤️
