Hi All, I am plotting a scatterplot of 21 populations, and I am using rainbow(21)[pops.col] to generate 21 colours for the plot (which works). Maybe it is because I can really process few colours at a time, but the differences between the colours are not as strong as I’d like. I can specify start and end for rainbow(), but if anything that looks worse if I do not just stick to 0 and 1.
Is there a way of getting a set of 21 colours that maximises the differences between them? I could pick them by hand, but that is about 15 colours more than I know (I have a detailed colourchart, but the visual differences between ’skyblue’ and ’slategrey’ elude me when plotted as dots on a plot).
