Add a warning prompt when picking a role colour which is not easily visible in light/dark mode

Hope this is the right topic. I've come into the situation frustratingly often where after I join a server, I immediately have to ask the admins if they can change certain role colours (usually white and light yellows) so the names are readable for light mode users like me. I can imagine the opposite situation exists as well, where an admin using light mode does not check whether role colours are visible in dark mode.

To prevent this problem, would it be possible to add some sort of warning when selecting a role colour about that role not being very visible in dark/light mode for colours such as light yellows, white, and dark greys?
