Text not readable with "rrt" style

[mewmew]

Hi Alec,

I've had great fun these last few days taking Chroma out for a spin!

Wrote a quick script that allows you to select the Chroma style to use. All works fine, except one it seems. The text of rrt style is not readable, as it uses black foreground text on black background.

PoC:

Cheers,

I see the problem, thanks for reporting it.

The issue happens because Chroma's rtt.go style doesn't recognise everything. If I look at the Pygments source (which Chroma is based on), then Pygments neither highlights that much. Here's a webpage with the output that Pygments makes, and there the rtt style also lacks highlight for various code elements.

With a bit of digging I did find here what Pygments uses for rtt. That source is, however, five years old. If it would be more recent, I'd use that source and make a pull request for this issue. But now I'm not sure what the best approach is.

Any thoughts? If that older source is okay, I'd happily send in a pull request.

@Jos512, thanks for diving into this problem!

I think @alecthomas would have to decide on the approach best suited.

I think it just needs a default text colour set in the theme. I'd definitely appreciate a PR @Jos512, thank you.
