How does Ultraviolet light work?
UV light is the same as any other kind of light or radiation along the spectrum from radioactive waves to radio waves. The difference between them is their wavelength and fequency. The longer the wavelength, the less the frequency. UV light is high-frequency short-wavelength light, just a bit more high-frequency than the highest-frequency visible light, which is violet. How does light work? Well, even physicists aren't quite sure.

Color is not seen distinctly in the moon why?
At a low light intensity, our color vision doesn't work, so we basically see in black and white. At a low light intensity, our color vision doesn't work, so we basically see in black and white.

What two types of light can be viewed from Earth?
This question needs refining as there is no 'type' of light. Light is an electromagnetic wave which is defined by its wavelength or frequency. As you increase the wavelength the frequency decreases and vice versa. A high wavelength/low frequency refers to light which can be described as infrared, microwave and radio (with increasing wavelength). A low wavelength/high frequency refers to light which can be described as ultraviolet, x-ray and gamma ray. In between the high and low end of wavelength is visible light which forms the colours that the human eye can see, you can think of this as medium wavelength and medium frequency. All of these 'types of light' are visible from Earth. Whether from decaying radiation, a heat source or a colourful painting. If this light originates from outer space then most of it is absorbed or reflected by Earth's atmosphere, but not all of it. This is how ground based infra-red telescopes work. In conclusion, all forms of light are visible form Earth as even the ozone layer isn't 100% impenetrable.

How do you make colors appear?
There are two types of coloring out there. Light and dyes. They work in slightly different ways. Light is electromagnetic radiation. The visible spectrum consists of red, orange, yellow, green, blue, indigo and violet. The difference of colors comes from the different wavelength of the radiation. When you look at sunlight, it is all wavelengths of the spectrum at once, and appears white. When you filter out all but one light wavelength, you see only that color of the spectrum. Dyes/paints work slightly differently. If you paint a wall in your house red, you see the red because the dye absorbs all of the spectrums of the light except red. Unlike light, when you mix all dye colors together, you get black because all spectrums are absorbed by the dye. You also see colors because when you see light, light is absorbed
