Wow, that's compact. Thank you for the programming insight. :)
Very neat! I thoroughly enjoyed writing this code
which agrees with your values (to within
I was perusing the ColorData schemes for a project and stumbled onto the partitions of these hues not being located at 6ths. So I decided to make an illustration of it and succeeded with some help from Hans Milton in this thread. To find the discontinuities I employed a telescoping algorithm to 1st determine the numerical resolution of the data, and then telescoped onto the locations. I've no idea why the data are this way - perhaps just some concatenations or generated from a different color coordinate system. There is at least one more like it in that collection.
Is this really where the divisions are? How did you extract that data?
