Okay... I know it's hard to believe, but the blue and green spirals in the picture above are actually the same color. I had to "eyedrop" them in a graphics program to believe it myself, but it's true. If you can't see the similarity at all, try looking at the very outskirts of the "blue" spiral and with less noise around it, you can start to see the blue look more green.
I don't know if it was the Phish concerts I went to last weekend, but the psychedelics are really getting me going this week.
