I'm sorry about the orange. I was trying to duplicate the original site. But it looks like it was more reddish.

That's the first I've heard of blue blindness. Are you kidding? And surely you are jesting about Viagra. What colors can you see?

I can see ALL the colors. The frequency of response for blue cones overlaps that of the rods.

Unfortunately it's not perfect.

The viagra thing came up when older pilots began failing color tests they'd passed for years ~ and I don't mean the ones where you look for the numbers and letters, but the other one which is used to detect ability to differentiate shades ~ USDA also uses it to test folks who grade vegetables and produce.

So, what happens on the net when you use orange or yellow? Basically the stuff gets fuzzy.
