hahaha that picture really is interesting now you mention it. I had just fed cyclopeze so it really gives the spot light effect. In normal conditions you dont see any spotlighting.
However the array is laid out as even as it could be. Its blue,white,blue,white down the length of each rail, and each rail is staggered. I think the gaps are from the 3 UV led's i have in the rails. You can see them in the array, as they are the ones without any optics.
The only time i see colour hotspots, is if the fish swim right at the surface, then they change colour a little. The rocks and sand have a nice blend. Again the photo does not quite show the reality.
More spectrum is needed though. Next build
