[Feature request] Accessibility functions

[Dallas62]

Hi,

I'm currently using this library to define color variations of the design system, and I was looking at some color palette tool such as Coolors which provide some accessibility tools.
For exemple:

It would be great to get an API to generate this color, such as:

Color('#FFAA00').filter('protanopia').hex(); // #DAD929

And It would be cool to get a global configuration, such as:

Color.global.filter = 'protanopia';

Color('#FFAA00').hex(); // #DAD929

This would help to switch the interface into blindness colors and test close to their perceptions.

It would be great to get an API to generate this color, such as:

This is a wonderful case for releasing your own package based on color :)

const Color = require('color'); // this package
const { protanopia } = require('color-a11y'); // your own package, perhaps

const filteredColor = protanopia(Color('#FFAA00')).hex(); // #DAD929

And It would be cool to get a global configuration, such as:

Global filters would be an anti-pattern here as it would affect all users of the package, so it's something I won't expressly support.

color-a11y is free as of writing on NPM, so feel free to create a package for it :) I would personally use it!

However, I don't see it being useful for the 80% of users that use this package, whereas a dedicated package would make a lot of sense here.

Good idea though :)
