The Thimble issue I chose was: https://github.com/mozilla/thimble.mozilla.org/issues/1100
The issue is that when you change colour settings on Thimble, it does not change the part under Files tab. This files tab is framed under Bramble. To fix this issue, I must identify where tab is in Bramble and figure out how to change the colour once the user selects different colour tab.
