Because its at the blue end of the light spectrum, visual light is in the middle (what we can see) and infra red is at the other (red end) of the spectrum. Does it appear blue? To whom? Or to what? Is ultraviolet and infrared light part of the visible spectrum? If not, then we don't know what they appear to be. A UV light source appears blue because the light waves it produces go down into the blue/indigo/violet frequency range. You can't see the ultraviolet light itself, just this "waste" light. There are two reasons they don't tune UV sources to just generate UV--it would be really expensive to build a bulb like that, and they want you to see the bulb's on so you won't look at it and harm your eyes.

What can happen if you can see ultraviolet light?
If human vision could detect ultraviolet light as well as the visible spectrum, ultraviolet light would appear to be just another color. Of course, because we can't see ultraviolet, and can only see three basic colors, the idea of a new color is impossible to completely grasp, since all the colors we see are based off of three primary colors. The addition of ultraviolet light to the spectrum of visible light would allow us to see more things, and some things that appear transparent would appear translucent or opaque, and make things we can already see appear more colorful.
Can scorpions see in ultraviolet light?
No. They can not see in ultraviolet light. They are known to glow when exposed to ultraviolet light, though.
