If you want to use crayon colors in R but you don’t want to rely on my R/broman package, you can just grab the code. Copy the relevant lines from the R/brocolors.R file:
crayons = c("Almond"="#efdecd",
"Antique Brass"="#cd9575",
"Apricot"="#fdd9b5",
...
"Yellow Green"="#c5e384",
"Yellow Orange"="#ffb653")
I spent a bit of time thinking about how best to sort the colors in a meaningful way, for the plot_crayons() function. But then decided to stop thinking and just do something brainless: measure distance between colors by RMS difference of the RGB values, and then use hierarchical clustering. Here’s the code from plot_crayons():
# get rgb colval <- t(col2rgb(crayons)) # hclust to order the colors ord <- hclust(dist(colval))$order
It’s not perfect, but I think it worked remarkably well:
