Do the colors Make a Difference?

Playing a round the other day, I was having a discussion with a guy that I met on the course and he noticed all my discs were blue.
He asked about it, and I told him that blue just seemed to be the best all around color for every season, in my opinion. Not to bad in the summer, spring and winter, and definitly the best color in the fall when all the leaves start to change and fall off the trees.
He started telling me that certain colors of discs may be more overstable than other colors. I think he said that darker color discs such as blue and green are more overstable that lighter colors such as pink and yellow and orange. I think that is what he said.
Is this true, do the colors really make a difference in the stability of the disc?

I have heard that some colors have a heavier pigment compound.

I know this to be true actually. We did a science experiment in high school where the weights of different dyes or food coloring were known and we layered them in a test tube just to prove that there were weight differences. I was pretty skeptical at first, but the test proved me wrong.

Actually, color does make a difference - white discs are terrible in the snow, black is tough at night and yellow or orange can be a real challenge in the Fall. Just kidding . . . sort of!
