Hi,

Thanks for a nice tool! 👍 I discovered it today since I wanted to get better outputs from tailing my Tomcat & application logs.

One thing I noted that seems to be missing from the feature matrix which would be incredibly nice is to be able to use 8-bit colors. They are supported by some of the modern terminal emulators - very nice since it gives a much larger amount of colors to select from.

The Ruby library which funnily is your namesake https://github.com/sickill/rainbow has this. Its implementation is particularly interesting, since it allows you to enter an RGB value (say #FF00FF) which will then be automatically converted to the closest 8-bit color code.

That makes the tool incredibly nice to use, but is obviously a bit more work. Just being able to specify these extended ANSI escape codes would be a good start in this area.
