Last night I was working on a talk on creating effective graphs. Mostly, I needed to update the colors, as there’d been some gaudy ones in its previous form (e.g., slide 22).

I usually pick colors using the crayons in the Mac Color Picker. But that has just 40 crayons, and I wanted more choices.

That led me to the list of Crayola crayon colors on wikipedia. I wrote a ruby script to grab the color names and codes and added them to my R/broman package.

Use brocolors("crayons") to get the list of colors. For example, to get “Tickle Me Pink, &rdqou; use

library(broman)
pink <- brocolors("crayons")["Tickle Me Pink"]

Use plot_crayons() to get the following summary plot of the colors:

You can install the R/broman package using install_github in devtools, (specifically, install_github("kbroman/broman")) or wait a day or two and the version with this code will be on CRAN.
