Click and drag your mouse to draw a picture

I am playing with some ideas trying to understand colorblindness.

The colors I used are from trying to figure out the RGB values from color blindness tests, but it is mostly a 'best guess'. If you know the right RGB values for each of the kinds of color blindness, I would appreciate it if you could email me.

Once you have drawn a picture you can view it in any of the modes listed on the left (or you can draw the picture in that mode.

If your vision is normal, you should be able to see the top mode.

If you have a certain form of color blindness you should be able to see the bottom one while people with normal vision cannot. (This is the one that needs the most work. If you know better RGBs, let me know).

If all else fails, try the mode in the middle.

Disclaimer: This is in no way meant to be a colorblindness test. For entertainment purposes only.

Note: I searched for an algorithm to randomly fill the rectangle with circles. I ended up developing my own. If you have a better one, let me know.

Note 2: I put the code in a single file so it will be easy for you to view the source. The underlying code is in JavaScript.
