Glyphs Mini Font Color

Hello there,
loving to make first experiences with Glyphs mini.
However, is there a way to change the letters’ color from black to grey (on white background)?
If this cannot be done regularly is there a way to do it by coding or plugin?
Best regards,

That is currently not possible. Only the background color can be changed.

Danke Georg! Kompliment für’s Programm!
