Colorblind test chart

Nice.
I'm deutero.  My biggest problem is identifying or even seeing shades, especially in artificial light. Once someone finds out I'm color deficient, I am usually obliged to be tested with "what color is..." for objects around the room.
My analogy for normal vision people is that they have 16 million color upgrade, I am stuck with the 256 graphics card.

I knew this ahead of time... but I'm a tritanope.  I have severe Tritan-/Blue-Deficiency, meaning I'm completely without blues, most purples and greens, and even some yellows and oranges.  I also wanted to post to let you know that I am using your chart on my blog.  Here is a link the-adventures-of-wood-wall.we… .  I also credited you in my post and included another link at the bottom.  It's another simulator that you might find interesting.    (Very nicely done chart by the way.)

The B is a LIE.

Wouldn't have seen the "G" without that drop shadow looking stuff around it.

This is really neat, faving it!

Well this is another wrinkle - apparently, I can perceive anything in the real world that anyone else can, but I can't pass a test to prove it.

I see the top photo exactly the way a normal-sighted person should -- it has clearly distinct reds, greens, oranges, blues, yellows and all. The second photo lacks red and orange hues, as does the third and although 2 and 3 appear similar, 2 is a little more greenish, 3 a little more yellowish. I could see the green G just fine, the red R I perceived as an ill-defined subtle blush of pink. The blue/violet B is easy to see. So if I'm not seeing the R, why do 1 and 2 look totally different, and 2 and 3 look pretty much the same?

Hm. I can see the G, but I had to look for it at first... it's quite faint. However, I don't seem to have Deuteranopia... nothing looks like the provided example of said condition, in my everyday life.

very interesting. i would like to switch color modes in my eyes on demand
