Dynamically change the background color of the tags depending on the root background color.

[VarunPotti]

Currently the background color of tags doesn't change dynamically depending on the theme.

There are 2 possible ways to fix this:

1. Ask the user to input in 2 colors, one for the dark theme and one for the light theme.
2. Use a library like color to automatically create the background colors for the other theme.
