ANSI ESC-sequences to color gemtext

[38;5;12mToday I found out[0m - [38;5;10msome gemini clients accept ANSI ESC-sequences[0m, as [38;5;11mwe know them[0m from the terminal, to show [38;5;1mcolors[0m. Nice ;).

ANSI Escape Sequences for color

as it seems - some gemini clients accept and interpret the ESC-codes.

Clients supporting ESC-sequences for color (AFAIK)

Lagrange (has issues if there is a line-wrap during a colored string)
elpher (the only one, who - so far - fully supports ANSI-sequences) Clients NOT supporting ESC-sequences for color (AFAIK)
Elaho (on iOS)
Amfora (I am a little bit suprised, because amfora is actually for the terminal?)

ESC[38;5;{ID}m Set foreground color ESC[48;5;{ID}m Set background color

UPDATE:

have a look at [a rant against using colors in gemini]. Sounds rather valid.
