Creating the Color of Sand
Many people do not believe me when I first tell them the two perfect colors in watercolor to mix to create a lovely shade of sand. Beach sand.
Purple + Yellow = Sand
I use MaimeriBlu's Permanent Violet Bluish and Indian Yellow. Just a tiny bit of each and a whole lot of water.
Purple and yellow are on opposite sides of the color wheel. When mixed together you get a neutral, in this case a tan.
You can try different shades of yellow mixed with your purple to see how it goes. A touch more yellow to warm it up and touch more purple to cool it off. The major component is the water, lots of it.
