Caption: A new study from Rensselaer Polytechnic Institute Professor Mark Changizi suggests that changing the color of hospital gowns and bed sheets to match a patientís skin color could greatly enhance the ability of a doctor or nurse to detect cyanosis and other health-related skin color changes. Perceived color on skin crucially depends on the background color. For example, the five small squares are identical in each of pictured boxes. The change and gradation of the small squares, however, are much easier to identify in the box on the bottom row -- which is the same color as the middle square -- than the hospital gown-colored boxes in the top row.
