Fans don’t know what to make of Billie Eilish’s shoes.

In a video on her Instagram Story, Eilish showed off a pair of Nike sneakers, joking that her dad was trying to claim they were coloured pink and white when they are actually not.

The only problem was that in the video she shared, the shoes did in fact look pink and white, confusing fans and summoning memories of similar optical illusions online.

In reality, the shoes are actually mint green and white.

As some fans learned, the white balance on the video image caused the green portions of the shoe to appear white, while the white parts appeared pink.

Some, though, were convinced that they were actually different shoes.

One follower helpfully demonstrated that with a bit of white balance tweaking on the footage Eilish shared, the shoes did actually appear mint and white.
