Over a period of time, I've done this on four different (uncalibrated) 
monitors, in Ubuntu, XP, OS X, and across my little Fujitsu P7120 
laptop, the iMac, the HP LCD monitor, a Dell LCD monitor, and an old 
Compaq CRT, I always range around the 40-60 area, this time, 43, on the 
laptop. (I'm not sure if the above variables have any relevance. I just 
include them for reference).

My areas of fault are mostly in the blue-green to blue area, with bumps 
in the reds, and down in the orange-yellows.

I'm not sure if this is down to calibration, or simply that I am one of 
the not insignificant percentage of males with partial colour-blindness. 
I often wonder at this when people start talking in strong critical 
manner about lens colour, white balance and skin-tones, as, while I can 
often tell the differences, I find that also quite often it doesn't seem 
to mean much to me even then (and certainly it doesn't when I can't). 
Large differences...yes, I can see and make changes accordingly then. I 
wonder, however, whether the subtleties are completely lost on me.

I think this is what leads me to greater comfort with black-and-white. 
Much like when I use a good, prime lens, and *know* it's at least sharp, 
I think I am biased towards black and white in my own photography 
because I then know that faults in the result are my own (whereas 
potential colour-blindness-related faults may be something I simply am 
unable to detect).

Basically, I don't have certainty with colour, and I'm rather fond of 
certainty. :)
