Use of Munsell color charts to measure skin tone objectively in nursing home residents at risk for pressure ulcer development.

Aims: To assess the feasibility of classifying skin tone using Munsell color chart values and to compare Munsell-based skin tone categories to ethnicity/race to predict pressure ulcer risk.

Background: Pressure ulcer classification uses level of visible tissue damage, including skin discoloration over bony prominences. Prevention begins with early detection of damage.
