Let me say first that I have been trying to write an updated tutorial post to reflect how I actually do color pattern analysis. Useful stuff: sliding landmarks for doing alignment on curved parts of an organism, batch-processing modifications, file organization, that kind of thing.

A good reminder about why color scientists care so much about light sources.

Sometimes you just need to tweak things by hand.

How to use the dichromat package to quickly simulate how a color palette would look to colorblind viewers.

Kei-Lin Ooi at the University of Melbourne has a very good question about batch resizing (excerpted from an email): I am using images from online databases and thus the images are not standardized.

How to combine the recolorize and patternize packages to perform quantitative color pattern analyses.
