Note I think supports-color uses the following. Not sure if True works, or works as well as for instance 2 or 3?

If FORCE_COLOR is "0" or "false" then force plain, uncolored output
If FORCE_COLOR is "1" or "true" then force 16 color ANSI output
If FORCE_COLOR is "2" then force 256 color ANSI output
If FORCE_COLOR is "3" then force full 24-bit RGB output

Might be worth trying out, and posting a screenshot of it working in this PR to demonstrate this works as intended?

Removed the space after the variable and also instead of True, set it to 2 to allow for 256 color ANSI output. Screenshot attached
