I was doing a bit more reading on clour spaces and came across this: http://en.wikipedia.org/wiki/Lab_color_space "Additionally, many of the "colors" within Lab space fall outside the gamut of human vision, and are therefore purely imaginary; these "colors" cannot be reproduced in the physical world. Though color management software, such as that built in to image editing applications, will pick the closest in-gamut approximation, changing lightness, colorfulness, and sometimes hue in the process" neat! k
