What colors to mix to get emerald cake icing?

Answer 1

If you are looking for a causation sort of colour, here's what to do.

I will assume you are working with the standard grocery store liquid colourants.

Start with a very light orange, 1 drop red, 1 drop yellow and mix well. This is most likely going to be way too pale, but as you can add colour but not remove it and you have not given me any idea how big a batch of icing you are working on... better safe than sorry. Next add 1 drop green (yeah, I know, sounds weird, I swear it works), mix well.

Then one drop at a time add red and if needed a bit more yellow. Mix thoroughly after each drop, remember it will dry down a bit darker so keep it pale.

For a darker skin tone use red yellow and blue in equal amounts (1 -2 drops each) to start. Mix well. Adjust by eye with red and yellow until you reach the desired colour.

Remember mix the icing very well after each drop of colour, it is time consuming, but saves you making too many mistakes.

Mix a bit of Leaf Green with Royal Blue, and just a touch of black. Always mix a small amount of color to experiment until you get just the shade you want. Once you do get just the color you want, be sure to mix enough color for your cake, since it is very difficult to duplicate an exact color.

Also, if you get the color you want, but it's just a shade or two too dark, you can lighten it with an icing whitener, starting out with small amounts until you reach the desired shade. Wilton makes an excellent icing whitener, which can be found at many grocery stores, as well as arts and craft stores, or any place that sells cake decorating supplies.
