A survey was conducted to assess the response of viewers to ad- verts in which the eye color of the main character was varied. Two digital photographs were created. In the first picture the character is looking directly at the camera, so the eyes can be seen. The only difference was the eyes, which were made either brown, blue, or green. In the second picture, the character has the same pose look- ing down so the eyes cannot be seen. A total of 222 surveys were used for analysis. The following table is produced by an analyst using a software package.
