Has anyone made navy blue by mixing royal blue and black for fondant?

Were the results satisfactory?

It is a cake for my niece - a family party - so it doesn't have to be PERFECT, but I also don't want to toss out a batch of MMF and start all over.

I'm not sure, but I'd only add black a teeny bit at a time. Americolor makes Navy gel color.

Yeah, I just found out that if you want navy you should buy navy.

CC went down right after I asked this ? so I went ahead and did royal and black: Half a jar of blue later and 4 drops of black it still wasn't dark enough. I went to Michael's to see if Wilton had navy but I could find "dark blue" in a spider man set. I'm going to try adding it my blue blob later tonight.

I wish there a store in town that carried Americolor! Going to order from GSA very soon...

Navy is hard to acheive even when you purchase "Navy" color. I did a US Navy cake which of course needed navy coloring in the fondant and I ended up using my Navy Americolor plus some black fondant.

you can also try sky blue, purple and tiny bits of black i know it seems weird..but the high school colors here are Navy and after tons of trials that seemed to work the best....best of luck!

I always add a little violet to royal blue to get a navy color. The icing needs to set over night to darken.

Okay. I haven't kneaded in the dark blue yet, so I'll add some violet, too (and probably more black).

Hey wait! I just remembered that I have a dark blue luster dust! I think I'll just do that, instead... much easier. I use it for denim on cowboy cakes, it's perfect!

I just did this yesterday for a basketball jersey cake. I did royal blue w/ a little black didn't like the results so added brown then just kept adding blue w/ a lil brown until I got it. I love how it turned out...

Of course when I tried the same technique trying to make navy w/ bc icing it didn't work
