Hi Hadley, Many thanks for your post. You're not wrong - i'm certainly finding it challenging, but i assumed it was because i was making some basic errors. My data are 15 types of behaviour, e.g. resting, alert, locomotion, etc. so i need to use 15 colours to tell each appart in a barplot which esentially colour codes the sequence of behaviours. Therefore i need all colours to be individually identifiable with no possible confusion between the 15. As you touched on colourbrewer and other packages typically use gradients for changes in terrain, etc, which is not what i need, and as yousay, they only go up to 12. But what is frustrating is that there are 657 colours, and i can see that i could pick out 15 colours that are all very different, but i can physically work out how i can do that. I that makes sense?
