a uv filter is meant to be neutral and affects your picture as little as possible.
a filter used for uv photography, i have never seen before. i hear it is rare, and very hard to use. it is meant for pictures like this in link below:
UV GALLERY
what you see mostly here in the ir/uv section is IR photography. it involves placing a filter over the lens or modifying your camera to achieve another sort of result. in short, techinical explanation aside, foliage glows, people turn ghostly, water turns black, among other things.
i have no idea what filters make your image more red, green or blue, i htink you are referring to the ir photos where color mixing is done according to one's tastes.
actually, to be honest, i am not even sure you know what you are talking about! what are you asking the question for?
