The Color Czar approves! From Jason Snell’s MacBook Neo review on, appropriately, Six Colors:

Yes, there’s a standard silver that will allow the Neo to blend in with almost every other MacBook out there. Indigo is a somewhat lighter cousin to the Midnight MacBook Air, a dark blue that will satisfy those who prefer their devices to be on the darker side. The more interesting choices are blush, which adds a pink pop to the traditional silvery MacBook look, and citrus, a bright yellow gold that’s undoubtedly the most aggressive laptop color Apple has made since the days of the tangerine iBook.
