My understanding of UV lighting is that it makes the colours of fish brighter and more amplified.

There shouldnt be ultra violet light in the hood of your tank, the only time UV light is used in fish keeping is in UV sterilisers where the water is pumped through a tube which is blasted with UV light to kill parasites and pathogens in the water, uncovered UV light is dangerous and can lead to blindness if you or the fish are exposed too long.
Are you sure it is an actual UV light and not just a flouresent tube with blue light? There are two varieties of blue lights for aquariums, Blue actinic lighting which is used in marine tanks and blue moon lighting which is used in freshwater tanks for night time viewing.

It culd be a black light which only illuminates the very blue end of the spectrum.

My understanding is that Ultra violet that is off the violet end of visible light (and similar to infra red, is invisible to the naked eye).
