It would be interesting to expose the diff function so we can get the difference between two colors.

What do you think about migrating the project to ES2015?

Many libraries (tinycolor for instance) and codebases use {r, g, b} objects to represent RGB colors instead of the currently supported {R, G, B}.

Would be open to a PR adding support for the lowercase keys?

It would be really great if this could support colour difference via alpha channel, like this lib written in PHP. 😄 https://github.com/donatj/AlikeColorFinder

Thank you so. much.

I bumped into this lib by search for checking color relevance. I got a python example which can order them by relevance using a limit as well. So instead of returning 1 color, it returns an ordered list with a preset limit..

Is such a thing possible?

This example transform the RGB values to a vector list and then uses .length. I dont fully understand/know what .lenght is though in vector lists. I was think 3d points, but since these are its different i guess?!

def relevance(rgb1, rgb2):
        if isinstance(rgb1, RGB) and isinstance(rgb2, RGB):
            relevancelengtn = (__class__.rgb_to_vector(rgb1) - __class__.rgb_to_vector(rgb2)).length
            return 1 - relevancelengtn / __class__.__relevance0
        else:
            return 0

your implementation of the ciede2000 algorithm doesn't return the correct value.
