This repository contains a SAS macro for generating colors in the viridis color palette.

But what is the viridis color palette, and why should I care? The authors of the related R package describe it quite nicely.

• Colorful, spanning as wide a palette as possible so as to make differences easy to see,
• Perceptually uniform, meaning that values close to each other have similar-appearing colors and values far away from each other have more different-appearing colors, consistently across the range of values,
• Robust to colorblindness, so that the above properties hold true for people with common forms of colorblindness, as well as in grey scale printing, and
• Pretty, oh so pretty.

The R package authors go on to provide a good explanation of why viridis (and its cousins) are superior to most other color palettes on r-project. It's a good read if you have time.
