Color accuracy


Color is one of those things we don’t usually think about too much, but for clinical services like dermatology, infectious disease, wound care, and others, color can significantly affect the diagnosis or impact the perception of the severity of the condition. Most of us have probably not calibrated our monitors for color accuracy and few possess the equipment to do so. Most current phones are quite good at representing accurate colors,  however, older phones such as those released around 2012 and earlier were significantly deficient in their ability to display accurate colors due to the limitations of the screens and the technology at the time. 

One solution is to make sure you have a way to calibrate the colors from images and videos. The easiest way is to ask that the person taking the picture place an object with known colors in the picture. There are several software products on the market that provide color correction solutions. Having the patients photographed or presented on video in an appropriate light is a critical and inexpensive first step for capturing accurate and consistent color. Most light fixtures can have their bulbs replaced with a “sunlight” or “true color” bulb, which refers to a bulb with a light that is in the 5500 Kelvin temperature range.
