Mr. Sanden offer's his reason for the success of his palette on one
of his web-sites. He can describe it much better than I.

After many years of using the exact same palette as Sanden, I began using his pro-mix colors as an addition to my palette about two years ago. My rational was that I was already creating some of these mixtures out of my current palette and it was taking me quite some time to do so, a process that I had been doing for years and knew how to do it pretty well I think. Why not have someone do it for me? I am not a full-time artist therefore time is of essence to me. Isn't that
one of the reasons we pre-mix anyway?
