I think yes because I related it to the lesson we learned in science in grade 4 where black clothes observe the Sun and other bright colored clothes don't observe the Sun. So i thought since brown is darker it obsorbed more light so it was more sensitive.

As conclusion, my experiment taught me that blue eyed people see better in the dark and darker eyed people see better in the light (like as in they are less sensitive to the light). Also all the eye colors had about the same vision on what number they saw on the ishihara plates.
