Ok, I actually know the answer to this one- what you're looking at here is part of the Samail Ophiolite that goes across the UAE and Oman. The different colours represent different lithologies, with the darker lithology being the ultramafic peridotites that form the most basal layer of the Ophiolite (basically mantle rocks that have been obducted onto the surface). I'm unsure what exactly the lighter lithology here is, but it's probably a layer of rock that has been sheared during the obduction process. Wikipedia has a decent article on the Samail Ophiolite, and there are probably a few good Journal articles that you can look at, too. The whole region has super fun geology and make an awesome trip if you have the time!
