Back in July, someone on Nail Board asked a question about why some polishes look one color on some skintones and another color on other skintones. In response, someone posted a link to a website that had the most AWESOME color optical illusion ever.
Our perception of color depends on a lot on what colors surround them. The same color will look totally different if surrounded by certain (different) colors. Take this example (borrowed from the aforementioned website):
The green and the blue swirls? Those are the same color. It's a mint green (incidentally, one of my favorite nail polish colors), somewhere between the lime green and the light blue that we see in this graphic. I totally didn't believe it at first until I downloaded the graphic and used Photoshop to sample and compare the colors in the swirls. Even then, I thought I was being had. But no, they are the same color.
How awesome is that?! :D
