Mysteries of Color

Edward Choi

This is your third case. This man was the investigator at the scene. When asked for his story, this is what he said: When I arrived at the scene, I realized it was a serious matter. I remembering seeing a shooting earlier that day, close to where his body was found, but I could not see the murderer because he was wearing a red shirt and had green hair. Due to my colorblindness, I could not see his face. But I am sure the shooting was related to the death of Mr. Jones, as the bullet I found in his leg would implicate a connection between the two events. To be safe, we did a second test on the investigator. To understand the second test, please click on the link. His results on the second test were:
