There is a great new color palette application by SHERWIN WILLIAMS
I tried it and it is pretty accurate.
If you find the colors too bold just use it as a guide by picking up the palette and using a toned down version if the color. Here are a few examples for your viewing pleasure.

I also dragged they toolbar button to chip photos directly from the net (second image).
Let me know how it works if you try it out. Have fun Chipping!
