For many years this multi-hued logo served well for Apple, however, it has since been phased out in favor of a
solid color logo (though the color of the Apple does vary). The man who created the logo (which wasn't Apple first logo)
is Rob Janoff.
Sync has a little story up about him, where you find out that Rob's boss wanted the logo to be a solid color, but his Steveness wanted it to be more colorful to 'humanize' the company (in stark contrast to Big Blue, I would imagine).
Perhaps one day we'll see Apple products sporting this colorful logo again.
