How can I make a font with colors?

I was wondering how I can put a color dot on the font, so that I can make an entire typefamily with blue color.

Now I just finished the type design with Adobe Illustrator, but don’t know how to add colors or color layers in the Glyph. My software version is 3.0.5 (3124) .

APPRECIATE IT !!!

Have a look at the COLR/CPAL tutorial:
