Does it support background color using ANSI?

[provCristianMaluenda]

Hi,
I am trying to set the background color using ANSI. The console looks fine, but xbar changes the color to the text and not the background.
I am using Python3 and the code is like:

HEALTHY='\x1b[42m'
UNHEALTHY='\x1b[41m'
NC='\x1b[0m'

print(f'{HEALTHY}dev{NC}')

Console:

xbar shows the text blue instead of the background:

I saw the example #703 but I can not find an example of a text with a colored background.

Thanks
