Modifying colours in modals


We’re having fun restyling Jitsi Meet to look more in keeping with our own colour scheme. A lot of the components are modifiable via the stylesheets in /css. However we’re struggling to figure out how modals like the one below are styled, in particular background and font colours:

It seems they are styled using a mix of the properties in the scss files and some of the JavaScript in the actual js code.

Where would I go about modifying just the background colour in that modal example above?

Figured it out, atlaskit…about as intuitive as most Atlassian products…
