Hello guys

I'm making a font and I want it to be hollow. Like the Agent Orange font for example. The problem is, that when I type with it on the red background, the inside of the font is also red. When I write on the green background, the inside of the font is also green. The border still remains black but I want also the inside to remain white.

I'm using FontCreator 6.5 btw.

Do anybody of you know how to fill hollow fonts with the color? It would really help, thanks.
