What food colors can I mix to achieve a light flesh tone color for my icing?

i use ivory from wiltons and it always looks like skin tone to me.

They actually sell flesh colored gel.

I use a the tiniest amount of brown.

If you don't have the fleshtone food color, try making peach icing and adding a touch of pink, with a faint dab of brown. It works pretty good.

I was taught using copper. Just a small amount and it really looks like flesh.

I've used Wilton Ivory as a base. Then you can add very tiny amounts of pink or brown to get to the shade you need.

I use Wilton Creamy Peach with a touch of Americolor Ivory. Works like a charm for me every time.
