I need to tint my fondant lime green. I used the kelley green, but it's not the right color. What else do I need to use? yellow maybe?

I made it once and I thought it looked pretty lime-ish. I started with lemon yellow icing, and added small amounts of grass green until I liked the color.

What CakeMommy3 said.

Also Americolor makes an electric green that would work really well too.

Here's a mixing chart (Chartreuse looks like it would be good):

I also like referring to this post (it has several different mixing charts for different brands -you'll have to go through the post - I believe there are at least 4 of them)

HTH!

Americolor's Electric line of colors are awesome!

leaf green + lemon yellow = lime green
