* Pink + Yellow = Peach/Light Orange: The yellow will neutralize some of the pink and create a warmer tone.
* Peach/Light Orange + Brown = Beige: The brown will dull the peach and create the neutral, earthy tone of beige.
* White (Optional): Adding a touch of white will lighten the beige if it is too dark.
So, in short, think of it as:
Pink + Yellow + Brown (+ White to adjust lightness)
