Sorry, but your question lacks very important information. Therefore a couple of questions to think about:

1.) Are you confident that acquisition of the images retains the actual color? You know, there are cameras with in-built color filters, you got lighting etc.

2.) Are you using the NI Vision Acquisition software? NI Vision Development Module?

3.) What are those "regions"? If color of pixels in the "region" differs: Do you want to calculate some "color average"? Do you want to check only for "color ranges"?

If you have the NI Vision Development Module, you should have an "IMAQ ColorHistogram" function available. It should provide what you are looking for.

Still, you have to make sure that your images are acquired correctly. This is by far not a simple thing (refer to this thesis for more information).
