Darken the orange color to make white text more readable [ FEAT REQ ]

[Hew-ux]

Is your feature request related to a problem? If so, please describe the problem.
I'd love to use the "Automatic contact colors" option, however I find it difficult to read the text when it selects the lighter orange color as the text background.

Describe the feature you'd like
To make the orange color slightly darker, or less saturated.

Or use a very dark color for the text.

qksms has some open tickets that may be relevant, I've been running into contrast issues too.

Agreed. The contact colors look great against a darker bg, but text color needs to be checked against bubble color readability scores for sure.
