Green Header - Dark Mode

### Your use case

A couple of lines are darker than the rest and are made more noticeable as the top portion is compressed. It is significantly less noticaeble in light-mode because the colour isn't as solid as in the dark-mode.


#### What would you like to do?
Make the green more transparent and improve the gradient effect.

### Have you considered any alternatives?

Reintroducing the design prior - halo effect.
