What colors can make a peach color?
You can’t really get peach from those colors alone. You need to add white to lighten or dilute the color. Red and yellow will make orange, adding white will dilute the color to a lighter tint. Adding more red will make it pinker, more yellow will make it more peach. If you mix equal parts of red and yellow to make orange then start adding very small amounts of black you will make various shades of brown. Adding small amounts of white will lighten the browns to tans.
