Unique hues, as recently determined by 40 observers using Munsell color chips, have been compared to published information on focal hues. While there is good agreement in the case of three hues, there is a significant disagreement (nearly 4 Munsell hue steps) in the case of green. An experiment was performed using mostly identical observers, identical color chips, and identical viewing conditions to have 40 observers determine their focal green hue. While their average unique green hue is located at Munsell Hue 2.75 BG, their average focal green is located at 2.5G, thus being in agreement with the average World Color Survey focal green. The result points to different concepts of the observers for unique green and focal green. © 2001 John Wiley & Sons, Inc. Col Res Appl, 26, 171–172, 2001
