Night mode contrast on messages with "Automatic contact colors" is too low

[briaguya-ai]

DESCRIPTION

The readability of white text on the automatically selected contact colors is quite low a decent amount of the time. It would be very helpful if darker colors were selected automatically when using night mode to improve readability.

STEPS

1. Enable Night Mode
2. Enable Automatic Contact Colors
3. Get a few messages
4. Try to read them

EXPECTED

The messages appear as white text on a dark enough color for the text to be easy to read.

OBSERVATIONS

The automatically selected colors are often too bright, making it hard to read the text.

Could you send screenshots of examples when the colors are too bright?
