### Problem Description

In our UI we highlight active sections with our main color theme (e.g. trending, channel and settings tabs). So to make the slider more integrated in our UI it would be nice if it also shows the active picture in the main color theme.

### Proposed Solution

Slider is based on main color theme on selected picture.

### Alternatives Considered

None.
