I am having a hard time getting my fondant a royal blue color. I have gone through two bottles of americolor and it is still too light. I need it the color of the Marine Corps dress blues trousers. Is there any way to get it that dark color?

either start with chocolate orrr color and let it sit a few days itlll get darker the longer it rest

You could try adding just a pinch of black to darken it

Thank you both for the advice! I did try adding a little black, but it's still too light. It is getting darker as it sits though. Should I add more black or would it be better for me to air brush it once the fondant is on the cake?
