Well, to be fair, with any discrete scheme this would come up. The first question is "is it useful to have a discrete scheme indexed by total number of colors and by color number?" No surprise that I think the answer is "yes"; I think Dr. Brewer's research shows that color selection in general, and her schemes in particular, are generally useful for understanding. Then if you want to support such a discrete scheme, you have to handle the cases when you haven't defined colors. The question then is "do you leave that up to the programmer" or "do you handle it in some reasonable way within the programming system", and I'd argue for the latter in the way I described above. I defer to you guys on what the interface should look like, but I'm a strong advocate of having an interface for discrete schemes.
