peach color rgb
If you have cadmium red you can probably rely mostly on that since it's practically orange right out of the bottle. For digital work it's less intuitive. What you want is a nearly-white color that has slightly more of an orange hue. In the RGB color space orange results from 2 parts Red, 1 part Green. Very light colors, however, require all 3 channels to be fairly high in intensity. You can get a fairly convincing peachy/skin sort of color with 250 red, 190 green and 170 blue. You can pull back on the blue a little to get more of a yellow color which is closer to a peach: 250 red, 190 green, 120 blue.
