i use a pentax optio s60. it's a basic point-and-shoot digital camera. haha, my dad refuses to get me anything else right now, and i can't afford a good digital SLR, even though i am finally realizing all of the limitations of working with this sort of thing. but as far as a nice compact point and shoot...it's great.
there are a couple of color filters on it, but they usually de-saturate the photos.
as far as colors go, it could be the camera, but i've used other cameras before and my photos have tended to look the same. i am generally more of a colorist when i paint and draw, and even in my clothing design. i don't photoshop. i think i weirdly just gravitate towards nice colors, and that's what and when i end up shooting. who knows...
