Progressbar count unreadable in light theme

[matbme]

Progressbar has LightWhite hard-coded for the progress count, which makes it impossible to read in terminals with light background.

Other colors such as the progress percentage also have a hard-coded RGB values. I believe they should instead use FgGreen and FgRed provided by the library.

True, we never tested against light mode. We'll fix that.

For the percentage, it's a bit more difficult. The percentage is faded between red and green. This is only possible with RGB values.

This is only possible with RGB values.

Maybe instead of using pure red and pure green, something like #BC0000 for red and #00B200 for green would look good in both cases
