How to create background colors with `pastel format`?

[thorstenkampe]

Is it possible to generate background colors with pastel format - specifically the ansi-bit-escapecode family? From what I can see, the colors only refer to foreground colors.

I think it would make sense to implement those or at least mention the limitation in the help.

I don't think it's possible, but that sounds like a reasonable feature request. Thank you.
