Ability to change the colours of the Support interface

Hello there,

Currently, active and inactive tabs have quite similar colours (with low contrast) - https://drive.google.com/file/d/1yf0d2J72rkvFwrfuYrl3HmyZWxvUdvTq/view?usp=sharing

Is it possible to add an ability to change these colours or even change the theme for all the "Support" interface.
