Current problem
In Look & feel, there is now the option to configure theme colors. However, this option is a bit hard to find, as both the "Theme colors" heading and the respective "Configure" button are smaller than all others in the Look & feel menu (you can check the attached screenshot for a quick reference). Besides it being bad for catching one's attention and strange in such a relevant Look & feel feature, it could also be an accessibility issue.
Proposed change
I suggest that the "Theme colors" heading gets at least the same font size as the "Sync theme across devices" heading, and that the "Configure" button is moved to below the text and increased to a more noticeable size.
