A photo of a woman's legs has some internet users wondering if their eyes are playing tricks on them.
An optical illusion reminiscent of the Blue Dress, White Dress controversy has some asking whether the woman's legs are shiny -- potentially oversaturated with oil or lotion -- or marked with white paint.
"Why are your legs so shiny?" one commenter asked.
The caption for the photo, which was originally posted on Instagram in September, tells the answer.
"I like the feeling of paint on my skin," the Instagram user wrote.
Some people said it was obvious the whole time.
