Mysteries of Color

Edward Choi

This is your seventh case. This man was with Mr. Jones in the Amazon. The judge asked him what he did with Mr. Jones in the Amazon and he described: I was with him doing some scientific research on snakes. We were walking along the Amazon river when we encountered a huge snake. I did not know what it was because the coloring of the snake was red and green. This made it so I could not differentiate the colors of the snake. By the time I had realized it was poisonous, it had already bitten Mr. Jones. I killed the snake with my gun and pried open its mouth to be able to suck out the venom of Mr. Jones. I immediately sent him to the hospital and that was the last time I saw him. After narrowing him down as a possible culprit, we did a second test on him. To understand the second test, please click on the link. His results on the second test were:

Photo #	What you see	Correct Ö Correct X Incorrect	Diagnosis
1	12	Ö 12	This shows he is normal, everybody should be able to see this one, even color deficient people.
2	8	Ö 8	Correct
9	21	X 74	This shows a Red-Green color deficiency.

From these results, we have classified case 7 is classified as deutan colorblind. This means he is weak green.

The next test we did on him was test 3, please click on the link so you understand what test 3 was.

Case 6 had a deutan color deficiency. This meant that he is weak in green colors. On the second picture, he colored the pattern red-green, as green red. This shows his green weakness because he thinks that the red is green as he cannot differentiate the green when it is around red.

The last part of the case testing was test 4. Please read test 4 to understand the final process.
