Starbucks Low-Key Released Color-Changing Cups & They're Selling Out Fast

Recently, Starbucks quietly released a line of color-changing cups and the new merchandise sold out super fast. The cups, which were available in the U.S. and Canada, change colors when exposed to cold liquid. Is there any better way to drink your daily iced coffee than in an Instagrammable, color-changing cup? Definitely not...especially in the warm summer months.

The cups are only available in a full, which retails at $16.95. Though it might seem a little pricey for a cup, if you continue to bring the cup into your local Starbucks location for your daily coffee, you'll save 10 cents on your order. Here's a look at the new cups:

These are the five color options and how they transform with cold liquid:

• Rose: light pink to coral red
• Citron: yellow to emerald green
• Sky: light blue to cobalt blue
• Apricot: light orange to tangerine
• Arctic: teal to raspberry pink

After the color-changing cups' quiet release, they quickly sold out. While Starbucks must be super happy the cups were a hit, the limited amount of cups available for purchase left some customers upset.

Fingers crossed the color-changing mugs pop up again ASAP! They really are so fun.
