Plots difficult for particular kinds of colorblindness #233

Namely, the first and last quantiles are G/R, which is a common form of colorblindness.

This issue brings up another interesting aspect (of open source software in general), which is to what extent do we try and make Alphalens accessible to people of various disabilities.

I think the color of plots is an easy one to deal with. This one came up because I was helping with a workshop and one of the attendees simply could not use Alphalens because of it.

What would be some other ways to increase accessibility? If there are additional one-line fixes, I think it would only be a good thing to carry them out.
