In rare occasions, isolating for a single colour hardly alters the image at all, except to refine the focus on the subject.
My sister's sheltie is the best model of this idea, being a tri-coloured breed: Black, white, and tan (orange hue), although I've also included a series of myself in this example to show how the same effect with orange can be applied to a ginger like myself. Not that the effect cannot be applied to other hair colours. In fact, I think black hair models would be an incredible opportunity to use pop photography to emphasize fashion by isolating for the colour of their top, pants, jacket: Whatever you want to highlight most to the consumer! Just pick out what aspect of the photo you want the viewer to see first, and removed every other colour - it really is that easy: And that's something I simply adore!
The range of opportunities for pop photography is endless: Check out some other colour progression series' below which will soon come to feature all colours of the rainbow.
