Also relevant in Dark Mode:

For me, the issue only seems to be apparent in the "Edit Tags" dialog, not on the email itself.

still happens and it make the app look unpolished.

Dark mode looks fine though:

The Tag Edit dialog is still an issue though in dark mode:

@miaulalala we had a brainstorm together related to this some time ago: #5217

is there anything on backend that can be done related to this? Or should i look it only on frontend part?

The default color is unfortunate but you should still expect ever color to work if the user can pick one.

the colors that are unreadable are tags that are auto-generated, like junk, redirected, spam, pishing ect. I doubt these tags should be shown there at the first place.

That's true, the tags in my screenshot were auto-tagged by my email provider. I wouldn't mind if they were hidden, but It would still be nice to know they exist so i have the option to (hopefully at some point) delete them (#5146)
