How do I get rich colors?

I believe UV filters cut out some haze, though I doubt it would have much, if any, effect on the resultant image.

While it won't cut all the haze, it will help. Haze is just light reflecting off lots of tiny water droplets in the air, usually at all different polarizations. The polarizer will cut light coming from just about all polar directions except two direct opposites (0 degrees and 180 degrees for example depending on the rotation of the device).

Try it, even on days without any noticable haze I use one to help give my skies a kick back to blue. And yes, as mentioned by the OP, greens back to green and so on..

using 'levels' in CS2 then shad/highlight and finally 'auto contrast/colour' you get a reasonable result in conditions like that the simplest approach is usually the one I take....... use 'P' setting and let the camera decide the exposure levels. same applies to Tv and Av a Tv of say 1/125 or an Av of f11 if its a really windy day then use higher shutter speeds (500-1000) to avoid any blurring
