Nice can you add the install of colorspacious to our .travis.yml file here

We are building the docs on Travis so we need the dependencies there too

Can we use colorspacious in the grayscale.py and Lfunction.py files in this directory too? That would allow us to get rid of color.py and the colorconf function there in. I modified the plots at some point to use an internal version of the colorconf function from scikit-image to reduce the dependencies when building the docs. I think depending on colorspacious is fine thou

I haven't done this before — do I just add a line of
pip install colorspacious
after line 81? I'll look at the other scripts to see if colorspacious can be used instead.

Thanks, Adding colorspacious to line 81 should be enough. I.e. it should read:
pip install $PRE numpydoc ipython colorspacious

You can ignore the AppVeyor thing. This is fallout from #5595

@kthyng Thanks!

backported to 1.5.0-doc as c234879

I have another PR (#5611) to address @jenshnielsen suggestion to use colorspacious, etc.

What's the mechanism for updating the documentation on the website? The old inverted image is still being shown on the Choosing Colormaps page.

The dev-docs are built automatically from master every time we push to it and are hosted at http://matplotlib.org/devdocs/users/colormaps.html

Updating the main page is a manual process which no one has done yet. We are going to do a 1.5.1 release this week which will include the updated plots.

@tacaswell Thanks, that's good to know
