[eyedropper] Compute "corporate colors"

[kptdobe]

The colors are currently things like text, links, background colors. It is certainly a tricky task but it would be more useful to extract the list of colors used on the site to create a "color palette". Each color from the palette would be named with the most approaching css color name (e.g. something like projectname-lightgreen). From there the text, links could use those colors from the palette.
Extracting the list of color should be trivial (for all DOM elements, get the color and background-color properties). Finding the closest matching color name is probably an interesting math problem.
