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.
