How so small?

There are two secrets that keep this lib especially small:

Simplicity — only handles basic color manipulation functions
Less branching in code — only support two color models as outputs, namely rgba and hsla

Why only `rgba` and `hsla` as outputs?

This lib was created with the use case of CSS-in-JS in mind. At the end of the day, all that matters is that the browser can understand the color string you gave it as a background-color.

Because only those two color models are supported, we don’t have to add code to deal with optional alpha channels or converting to non-browser supported color models (e.g. CMYK).

We believe that this lib is sufficient for all of your color manipulation needs. If we’re missing a feature, feel free to open an issue 😎.
