I have a friend who is involved in a project looking for genetic links to behavior traits - one of the possible branches of that study will be this very question - whether pigmentation has anything to do with behavior/temperament. By the way, if you'd like to contribute to this study, it's very easy - just a questionaire and a cheek swab -
http://psych.ucsf.edu/K9BehavioralGenetics/ It is open to all breeds and mixed breeds.
The color superstitions are much stronger in the Border collie, which has been bred throughout its history without regard to temperament issues other than what makes a good working dog. Dogs with nasty temperaments don't tend to work well with people and make really lousy under-the-pub-stool dogs - the pub being where most shepherd and their dogs ended the day.
Anyway, they say that red (bb chocolate, like a lab) dogs are highstrung, weak on stock, and tend to be pressure sensitive. I have to say that I've known very few red dogs that actually went against this stereotype. Actually, I can't think of one. Red runs through every major line, so it's not a founder phenonenom. However, there are highstrung, weak, and pressure sensitive dogs of every other color. It's just not as consistent. My friend who is on the K9 genetic behavior project actually started out poo-pooing this superstition - she has a red dog herself - but as the data come in, she is starting to wonder about this. She says there's starting to be strong anecdotal evidence that the bb gene may be linked to some behavioral issues.
Some people say that all else being equal, the tris will make better trial dogs as they take direction beeter. I've had a bunch of tris and they've been all over the board on this one, I don't really see it. But I've kept to tris within the same lines, so that might factor into it.
There's a prejudice against merle because it is said they have a hard time getting sheep to respect them and they are too cautious on stock and i've also heard they have trouble flanking square (in other words, they don't "feel" stock well). Other colors are simply ignored now as they appear very rarely and their appearance is viewed with great suspicion.
Anyway, what I was going to say before I got sucked into all this, was that the show breeds have been bred speciically with a view to a narrow range of temperamental types (compared with the Border collie free-for-all). I think it would be interesting to compare the two populations, since they had their origins with the same stock way back when. I think the show breeds allow all colors but the red, so selection pressure would be against oddball personalities within every color.
