为 Matplotlib 设计更好的默认配色（SciPy 2015）

SciPy 2015 talk by Nathaniel Smith and Stefan van der Walt on choosing a new default colormap for Matplotlib. It covers why Jet misleads, how perceptual color spaces work, and how viridis was designed.

Why HN likes it: HN's go-to recommendation for colormap and color-perception questions; commenters call it funny, brief, clear and a favorite talk.

“This hilarious SciPy2015 talk[1] convinced me to switch to the Parula color scheme.”
