Once Upon A Time would meet most people’s idea of what a true Kelly Green should look like because with a hue family notation of 1.94 G it plots out on the color wheel over near the green-yellow hue family. Kelly Green, while considered a “true” green, leans more towards green-yellow rather than blue-green. Whereas true greens that lean towards blue-green colors would be labeled as Emerald Green according to the average observer.
