Ansi colour markup - what encoding or mime type

[Brian Evans]

My 2 cents:

Colors are really fun for those in terminal clients that support them, 
but seem to be a pain to build out for graphical clients. So expect 
failure. I really loved Konpeito's color banner and really like occasional
touches of color. However, full pages of colors tend to get weird.
Subtle is the way to go to provide a splash of fun.

My client, Bombadillo, has 'normal' and 'color' modes. In normal 
mode all escape sequences are stripped from text/gemini output. 
In color mode escape sequences dealing with color and text style 
(but not placement) are rendered as the escape sequence so that
the effect can be seen.

I advise client authors to strip escape sequences if they do not wish
to deal with color output or terminals potentially getting really
donked.
