red green gray illusion

I was designing a web banner with red, green, and gray. I thought Photoshop was doing something weird with the gray. The gray was showing a red tint. It wasn’t the opacity setting or any sort of blending effect. It just turns out that when you sandwich a strip of gray between red and green the gray will appear to have a red tint.

Josef Albers would be proud.

They look like the same color gray to me. OH wait, the more i stare at it, the more it turns red. Ok. it’s kinda red now.
