How would I come up with the color of Midnite Navy Blue? I need to color some gumpaste.

Americolor Navy Blue worked for me on my Braves cake in my gallery. It took a bit but worked great. Just remember that it takes time for the color to develop. HTH

I colored my paste for this Faberge egg with Wiltons Royal Blue, when the egg was dry I dusted it with Cake Centrals Super Blue luster dust. If you need your finished item darker you could always spray it with Americolors Navy or Electric Blue, it is quite dark.
