The intent is not to retrict the use of Kuler and Kuler themes for use in design project fo any type. If so, we would not have included access to Kuler in many of Adobe's profesional design products.
I've asked for clarification from Adobe Legal on this and will post as soon as it's received.
Still waiting on a formal response from Adobe legal.
However, pending a formal response from legal, the Kuler team's understanding is that our users would apply Kuler colors to a wide variety of creative projects, which includes commercial work.
