There was a lot to celebrate at Apple on Monday morning. The company announced that it set a new sales record for an iPhone opening weekend: 9 million phones in three days.

The company declined to break down figures separately for each of its two new smartphones — the iPhone 5s and its lower-end iPhone 5c — but said it has run through its entire initial supply of the higher-end model.

“The demand for the new iPhones has been incredible, and while we’ve sold out of our initial supply of iPhone 5s, stores continue to receive new iPhone shipments regularly,” release, Apple chief executive Tim Cook said in a release. “We appreciate everyone’s patience and are working hard to build enough new iPhones for everyone.”

The sales figures outstrip analysts’ expectations for the opening weekend. Estimates for the phones’ sales ranged from 5 million — the number of iPhone 5 models Apple sold on that model’s opening weekend — to 8 million.

Company stock opened up 5.2 percent to $492 a share.

Apple didn’t specify which iPhone colors were the big favorites with consumers, though more anecdotal reports suggest that the gold iPhone 5s was far more popular than the silver or “space gray” models. The gold version was the first to run out on Apple’s Web site, and several customers reported that they were having trouble finding the phone in stores if they weren’t at the very front of the line.

As for the more colorful, plastic-backed iPhone 5c, at least one firm estimates that nearly half of its customers favored a blue or pink phone. Slice, an online firm that helps users track their online purchases, reported that 28 percent of pre-orders it tracked for the iPhone 5c were for blue phones, 20 percent for pink phones.

What was the least popular color for the iPhone 5c, according to Slice’s data? Yellow, which accounted for 10 percent of the orders.
