Like the others have said- you don't have a UV or Ozone light in that fixture.
The two white bulbs are called daylight lights & the two blue bulbs are called actinic lights. The daylight bulbs cover a lot of the visible light spectrum so all of the colors show up (basically how you'd see things if you were outside). I think they range from around 5000 kelvin to around 7500k.
The actinic lights are around the 420nm range, which gives off a blue hue & make colors fluoresce.
The LEDs are most likely moonlights, or "mood lights".
UV lights have to be shielded because they're dangerous (not entirely sure what makes them dangerous or what an unshielded bulb would do to a human) and they're used in UV sterilizer units, which are meant to kill pathogens in the water.
