The database was searched for the clinically relevant colors, Black, Yellow, and Red, on the Wound Healing Continuum.8 Four of the photos were consistent with the target RGB for Black, zero for Yellow and Red. Researchers have proposed that accuracy and precision within 10% as sufficient for measurement of wounds.10 This research documents significant color inaccuracy in photos with only 4.23% of Black, 1.66% of Yellow and 2.02% of Red photos meeting the 10% accuracy threshold. 62.29% of the photos were 50% off from the target RGB values.
