Joe Wants To Know If I am Colorblind

Actually, yes I am, when it comes to blues and greens! Sometimes I see green where others see blue, which I suspect is what happened here, and why I did not get the fact that the costume is a BIG BLUE DRINK! That and the fact that I saw it late at night. And was half-crocked.

I also see the yellow traffic light as brown. I have always called it brown, never yellow.
