Collecting qualitative colour palettes

2021-08-21

I have been curating a personal R package for a few months now, to try and organise the many snippets of R code that I tend to reuse in different projects. The package isn’t on CRAN, but it is on Github for anybody interested. One of the functions I keep is essentially a list of qualitative colour palettes. Some are my original creations, but most are lifted from other packages, or examples I’ve seen somewhere online. It’s incredibly difficult to come up with categorical colour schemes for more than about five categories, and it can be frustrating trying to find colour combinations which maximise readability across a range of colour-blindness conditions, and which look good.

These colours come from CARTOColors :

The function, in case you want to just copy the hex codes:
