You mean fuchsia?
I suppose you work with those edible colors, huh? Hmmm... they sure mix differently than those I work work with.
Let's try this: (I hope we think about the same fuchsia,cuz there are
several of them)
Use the reddest red you got, add a bit of indigo blue, and if it gets too dark, a wee bit of white.
If that doesn't work, we'll try something else. Good luck! And try to mix colors on a daylight!
