This is because your hair is more than one color ;)
The iSight camera and the histogram does per pixel comparisons, so
depending on lighting, the histogram will decide your hair pixel is
closer to one particular color in your map than another. Since the
colors are not smoothly ramped, but somewhat posterized, you will see
your hair changing color as the histogram changes its mind.
I think the technique ("chunking") is simply nearest neighbor
interpolation vs linear, no?

I don't know if that is because of the iSight camera or the
operation is dependent on overall quantity of a color in an image.
