The purpose of color-lab is to compute readable colours.

The use case is this:

Given a constant background colour in a buffer, you then have a <p
style="color: blue"> HTML element.  If you have a white background, then
that's fine.  If you have a black background, the blue colour will be
unreadable.  color-lab computes a "distance" between black and a blue
hue that is readable, and that blue hue is used instead.  It's kinda
neat. 

So it doesn't have much to do with hexrgb.el, I think.  Did you read the
code?
