@stefan-dragomir instead of black, we should check if another shade of same color can be used to fix contrast. if not possible, then confirm with XD once

Black was the designer's suggestion to make the tab color more striking since we can't change the tab's background color.
Also moving this to a PR raised from Main instead of Fork. #22
