Analogous colours seem to be wrong?

Looking at the code, does rotate -30 work? Shouldnt the array return 3 different colours rather than the current two?

It should return 3 array items. Could you please post an example of it not returning 3 colours.

sorry, yes it does return 3 items, but two of them are the same. Should they not all be distinct/different?
