exposure time and color

Has anyone had enough experience and seen if exposure time will effect the final colors in a photograph?

I'm wondering about this because it seems reds are more prone to overexposure and could this error be because the camera metered the scene wrong, or that the canon sensor is more sensitive to reds than blues, and greens are the least sensitive since they often turn out black in photos.

And in a photography sense.

Say I can take a picture using.... 1/2s, 1s, and 4s shutter speeds and all of those speeds will have enough depth of field. ISO can be changed to get acceptable aperture sizes. Will the final colors of that photograph be different? Oh yeah, also assume a static scene, meaning no moving fluids such as waterfalls, or objects that can cause blurring.

In certain situations, particularly cityscapes, the light pollution can give and orange-brownish tint to everything if you keep the shutter open too long. It could be corrected to some degree in PP (adjusting WB, desaturating certain channels,etc...) but it's easier to work with if you can control it while you're shooting.
