Does Eye Color Affect Color Sight?
Procedure
I chose three pieces of construction paper that are all different colors.
I turned off most of the lights in the room that I used until it was dimly lit.
I then taped the three pieces of paper to the wall, and brought the test subject inside.
The test subject then wrote down what shade/color they saw.
Variables
Independent- different eye colors
Dependent- color sight
My Hypothesis
I think eye color has an effect on vision, but a very, very subtle one.
Blue eyes will probably see lighter colors because the pigment in their eyes are much lighter than brown or green.
Background
In this project, the purpose was to see if different eye colors (brown, blue, green/hazel) saw colors differently in a dimly lit room.
Conclusion
This experiment evaluated whether a person’s eye color affects their ability to identify colors in a dimly lit room. Studying the human eye and color sight is something I had never done before. However, once learning the anatomy of the eye, I had created a project designed to study if color sight is linked with the color of the eye.

In a way, my hypothesis was both right and wrong. I figured that blue eyes would see the lighter colors than brown or green, because the pigment in their eyes are lighter than others. When analyzing results, I found that humans with brown eyes tend to see darker colors than blue or green eyed people, at least for the eleven- to-twelve age group. Human eyes change as they grow up, so it was important to have test subjects of all the same age group. The blue and green eyed people saw around the same colors, which were usually light.

This was, overall, not a very difficult project to organize. However, if I did this project again, I would probably choose to make the testing process more organized. It was a little bit hectic, because in the classrooms I was using, people would come in and out, and accidentally turn on the lights so the subjects were able to see the color. It probably would have been easier if I announced I was using the room. Another thing is, I would have planned out and completed my testing much earlier, because it was difficult analyzing the data so quickly.
Problem Statement

dimly lit room
Questionnaire (asking test subject what color they see)
tape
45 test subjects (15 with brown eyes, 15 with blue eyes, and 15 with green eyes)
Brown Eyes Results
Blue Eyes Results
Green Eyes Results
