Hi Phillip,

I just checked out the code, and I'm not clear about some things: What is the gamma transfer function you use to convert from linear RGB to "normal" RGB for displaying? You were correct being suspicious about using 256.0 instead of 255.0. Do you happen to have the according Rgb2Lab function as well? Now I question my old routines.
