As I recall, the original Bondi blue iMac was the best selling model of personal computer at the time. This wasn't because Apple suddenly stopped being the Betamax of the home computer world, it's because there was only one model when everyone else had a full range, and the effect disappeared the moment they came out in multiple colours.

Same deal with Tesla: They have two core models (Y top, 3 next, all else a rounding error), while everyone else has a full range that sales are split across.
