color ascii art

Hello,

I am writing a dos based shwareware program. The graphics are color ascii
and ansi. I am looking for text based color graphics (non gif, non tiff,
non pcx...) that are not what seems to be called "ascii graphics" where
letters and numbers (instead of drawing characters) are used to make the
graphics. For exampl,e, very nice graphics can be created in text mode
with the draw, using dos drawing characters, but avoiding the use of
letters and numbers which look a bit too rudimentary for my program. Where
could I find a library of such graphics ? 

Thank you for your time and help,

Jean Lette
