Customizable colors for languages in language card

### Is your feature request related to a problem? Please describe.

Although it most likely doesn't happen with everyone, the languages card has a very similar color for HTML and Jupyter Notebook, which hurts distinguishability when viewed together in **compact** view.

### Describe the solution you'd like

It would be great to have the ability to assign color of choice to your languages in the languages card.

### Describe alternatives you've considered

The color of one of these two languages can be changed to fix the issue in this specific case.

### Additional context

## This is what I want addressed: Very similar colors adjacently hurt distinguishability.
