And the original design was just a single color Apple (which, of course, Apple has used versions of since), but Jobs thought the design should be more colorful, so the logo got its familiar colored bands. Janoff says he just threw the colors in where he thought they might fit, which makes sense -- they don't match up with the physical spectrum at all, they're just sort of in there.
Cool to see that something now so well known started off so simply. Janoff did the work for a design firm, and says that nowadays, he gets "not even a holiday card" for his invention. Apple does take their time recognizing inventors, though -- maybe the card's in the mail.
