This is neat but there is something quite wrong with the protanomaly/protanopia simulation. Look how it effects blue:

It adds a ton of red instead of removing it. Blues should be largly unaffected by protanomaly (though purples will turn to blue)

I think you're right, I'll look into this. Thank you!
