Color-Blindness Simulator

Did you know some people have normal vision in one eye and dichromatic vision in the other? Not sure why (chimerism, I suppose, or some acquired trouble with the dichromatic eye) but it's a great help to the rest of us.

If you guys want to have some fun, use this. It's a color blindness simulator; it modifies images to make them look the way they would through different eyes...sort of, but it's technology, not biology, so what can we do?

OBLIGATORY WARNING: What you upload to colblindor.com stays on colblindor.com.
I said, "What you UPLOAD to colblindor.com STAYS on colblindor.com!!"
*Actually, I think uploading another image with the same filename and color setting replaces the previous one.
I'm glad I realized that before I uploaded a personal image...I mean, not that I would do anything naughty.

Geek moment: While sorting through my modified images, I was listening to the Symphony of Science and heard this beautifully autotuned (teehee, oxymoronic?) line by Neil DeGrasse Tyson:

When you're scientifically literate, the world looks very diff'rent to you, and that understanding empowers you.
