Preferred memory and accent colors shown on a display

Abstract

The preferred green-grass and red (apple, lipstick, sports car) colors shown on the display are investigated using complex images. Ten test images were used in the experiment and each image was transformed using a memory color transformation algorithm to have nine different green-grass or red colors. The pair comparison method was used to determine the most-preferred green-grass and red colors. The green-grass colors are preferred as the average hue angle approaches 128° (60% green and 40% yellow) in CIECAMO2 hue angle with high chroma. For red colors, apple images show high preference when the reproduced red is closer to the unique red. The artificial objects, such as red lipsticks and sports cars are preferred when reproduced with the highest chroma regardless of their hues.
