Optical illusion of two girls stumps internet

If you feel like tricking your brain, we've got just the thing for you.

Akiyoshi Kitaoka is an experimental psychologist at Ritsumeikan University in Japan. And by the looks of his Twitter page, it would appear that Kitaoka has an affinity for confusing the internet by sharing optical illusions he creates from scratch.

One illusion of Kitaoka's in particular involving a photo of strawberries became a viral sensation recently. But we've found another one of his images that has left tweeters befuddled.

Optical Illusions

TONED ARMS

Queen Bey certainly doesn't need the extra strength training, but her post-pregnancy style involved lots of three-quarter-length sleeves, which elongate arms and disguise any excess flab. 

STREAMLINED MIDSECTION

If you're worried about a little extra tummy peeking out from your jeans, opt for a high-waisted pair that will skim over any worrisome areas. Claudia Schiffer pairs hers with a plaid shirt for a casual look. 

SLIMMER THIGHS

For thighs that appear smaller than they are, choose a pair of wide leg trousers that draw attention downward, like Jennifer Hudson's sleek pair. 

TALLER

Pick a short dress in a solid color like Selena Gomez's here, to appear longer.

LONGER LEGS

For a long-stemmed look, pair nude pumps with bare legs to make them seem like they go on for miles. Choose a pair that matches your skin tone - a classic trick of the eye!

SLIMMER ALL OVER

A pair of plain, non-distressed, good ol' denim streamlines just about everything and won't draw attention to any insecurities. Reese Witherspoon knows what we're talking about! 

BIGGER EYES

Lauren Conrad must know that a classic cat-eye is the surest way to open up eyes and make them appear bigger than they are. 

DEFINED CHEEKBONES

Kim Kardashian is the queen of contouring, which is what cheekbones are all about. Use a contouring brush to sweep bronzer in the hollows of your cheeks, along your hair line, and over the bridge of your nose. Voila - instant cheekbones! 

SMALLER BUST

For a smaller-looking bust-line, wear a scoop-neck top like Sofia Vergara's. It draws attention upwards! 

SMALLER NOSE

Stars like Kaley Cuoco have admitted to learning this trick in the makeup artist's chair! Apply foundation one shade darker than you would normally wear to both sides of your nose and blends towards cheekbones. Then apply a highlighter to the bridge, which is the thinnest part of the nose, for an all-around slimmer look!

At first glance, the hair and clothes of the girl in the right image would appear to be black, where those on the left are white -- right?

Wrong.

As Kitaoka explained to confused tweeters, both depictions of the girl were made using the same RGB stripes.

The RGB color model is a complex system in which only the colors red, green and blue can be combined in a variety of ways to obtain every color within the color spectrum.

Yet, the hair and clothes somehow look different to us anyway.

Similar to Kitaoka's strawberry illusion that stumped the internet - the girl illusion is created by a phenomenon known as color constancy -- the ability to perceive colors of objects, invariant to the color of the light source.
