(CNN) – Starbucks showing its true colors with a new cup.
Monday, the franchise launched its color changing cups, and stores are already selling out.
Coffee lovers who managed to get one, are reselling them on Ebay for a higher price.
The cups switch hues, based on their temperature.
So when you put something cold in them, they transform into ombre’ shades.
There are 5 different colors, plus straws and lids.
You can get one for just $16.95 and are eco-friendly.
