Thanks! Colormath does an amazing job handling the mathematical conversions between color spaces, but has (at least to me) a somewhat verbose API. Spectra wraps that API in something simpler, and adds scales, ranges, blending, brightening/darkening, and saturation/desaturation.

Spectra uses grapefruit for parsing HTML names and hexcodes.

I'm most excited about the color scales. It looks like a helpful tool for situations where the standard colormaps in matplotlib/pyplot don't work well. Is that an appropriate use case?

I also like seeing nbviewer used for documentation, I haven't seen that very often.

Yes, that's definitely the type of use-case I had in mind. Another big one: Choropleth maps.

Glad to hear it! It's my first attempt at writing documentation in an IPython notebook. Seemed like a good fit for something so visual.
