Isa Browns, color question? May be a stupid question

[tororider]

What color are ISA Browns? Their name would suggest that they are brown, but my neighbor, who I have gotten my hatching and eating eggs from said he was told his white hens are ISA's. I am wondering if that is the case or if he was told wrong and they are white rocks. If ISA's are indeed white, can they be bred with a RIR roo as a sexlink? Thanks

Here's a pic of his hens.

I have 6 Isa Browns, you can see their color in this pic.

The closest 3 are indicative of the coloring of all of them.
