I went and picked a nice image of some cherries that I thought would be good to recreate. You can get the picture of the cherries at Stock.xchng. Place the image in a new document on its own layer and lock it.
We will need to set up some base colors for our cherries. With the Eyedropper Tool (I), I picked five base red colors with one highlight color. I have illustrated below which ones I chose. You can of course choose more, if you decide to go into more detail.
