Definitely. Every time I move my machine to a different location i need to
re-calibrate the color/gamma/ect...

however, for what i am doing, i don't really need 100% accurate colors. i
would just like *some* automated way of going from colors defined like this:
2.5YR 5/5  into something that can be read by a machine- RGB, HSV, ect. I
suppose that it would be possible to create a giant lookup chart, but that
would not be as much fun as an automated approach... :)

thanks for the input!
