Actually I wasn't. In this case, the whole package was those colors, without any beige anywhere.
As for Apple, back when the iMac first came out and then a while after the color iMacs came out, I was browsing CompUSeless and in the Mac area four of the color iMac cases, with fake panels for the screen and no internals were shoved into a corner on a low shelf. I looked at these empty cases (which were there to demonstrate colors without having to stock four more whole computers) and went up to the manager to find out how much to buy one. He got a quizzical look on his face, asked me to hold on, and he went back to his office to do some checking. He came out about ten minutes later and apologized that he couldn't sell me one, because it turns out they were still Apple's property. He then asked me why I wanted one. I replied, "I want to make a fish tank!" He burst out laughing.
At this point I don't think anyone had made fishtanks out of the color iMac yet, because they were new and expensive. I wanted to be the first on the block with one and for people to wonder how/why...
