mine never get that rich in color and i make my own mmf and have americolor

Maybe you aren't using enough color. I use Satin Ice and get great depth of color with Americolors. I don't make my own fondant, so I don't know if perhaps that could be the reason - although I don't see how using MMF would affect color.

I have always used Wiltons and they all come out bright and intense..

I also use MMF and it does tend to like pastels best, but as you can see in my pics. I am also able to get dark bold colors just by using lots of Americolor....keep trying!

Buy it pre-colored. (certain colors)

i hate boxed fondant yuck. mine is yummiloicous

Boxed fondant? You must be talking about Wilton. Taht stuff is truly the worst tasting. Try SatinIce - yummy. The pre-colored SatinIce is great to have on hand. Makes those darker colors easy!

as leah says, pre colored satin ice. The taste is good and colors are rich and bright.

Yes, I'm surely not talking about any fondant in a box (especially Crapton!).

I love using Satin Ice in black or red, saves the time and trouble of trying to get deep colors.

I'm also on the satin ice bandwagon. I buy all of their colors and just blend those for custom colors. I can't be bothered coloring fondant with gels... too time consuming and messy!
