Just my own observations here:

I had my red phase Saharans under regular heat floods and a fluorescent UVB bulb about 18" away (which equals almost no UVB reaching the lizards). Recently I broke the fluorescent hood, so I tried a mercury vapor bulb as a replacement. Within three days, both of them were far more vibrant than they were under weak UVB.



I don't know enough about supplementation to keep them without any UVB. Mine never see actual sunlight and the MVB brought out their color quite a bit. The reds were redder and the blacks were blacker on both the male and female. I'm a believer.
