Difference in star colors

Hi all:

I took the attched frame from a vid I shot last night with a Toucam. I simply picked out a spot in the sky with my scope, plugged in and adjusted the webcam and started recording. The area of the sky that I picked up on was about 120 degrees in azimuth and ~ 40 degrees altitude from my position.

When I processed the vid into individual frames and used Paint Shop Pro to (only) adjust brightness and contrast, I noted what I hope appears in the attached shot - stars/objects of various colors, mainly white, blue and red.

What do the differences in colors mean in terms of the object(s)??
