Mixing a peachy colour, you mix red and yellow, using more red to get a pinkish colour and then add white.
So essentially a light orange with a small amount of pink added.
I'd say yellow and orange or yellow and pink, pink and orange tend to make a darker color.

white and light pink, or white and orange.
Red and white i would have thought
