I am trying to make Navy blue without an actual navy blue color gel... Wilton says to use a combination of Royal blue and black, but this just makes a weird medium blue. Any other suggestions? I have almost every other Wilton color, I think, but my local craft stort didn't have a Navy blue.

You will need to go a very dark blue before you add the black. Approximately 1 tsp of wilton royal blue color for 1 cup of white icing and then add a small amount of black. If it is a little off sometimes the addition of a tiny bit of violet will help.

Thanks for your help, I'll give it a try. I was getting a super-ugly blue/industrial/institutional blue. I wouldn't recomment it! I have to nail this blue, though. I'll keep you posted, thanks so much for quick replies!

I just tried this this weekend and I couldn't get it to work. Like yo I got a ugly industrial color but it makes sense really because BLUE is a primary color and you can't combine colors to get navy blue, just dirty up the "royal blue" but I tried, no success.

Thanks anyway! Looks like I'm going to have to go online and order some Nave from AmeriColor or something.

Okay - sorry it didn't work. I was going by color charts and truthfully I use americolor mostly except for when I am teaching. You will love Americolor - It is wonderful!!!

always had great luck with mixng wilton or any other brand of royal blue with little touch of black to make navy.

I've also had success mixing royal blue and black, but like a previous poster said, you have to add A LOT!
