Besides, the proposed method is not limited to color images like [15, 16].
Upon a closer examination, this pattern is primarily limited to color pairs with similar lightness levels, which suggests that hue contrast is more preferable only when there is minimal lightness contrast.
It might be considered that the utility of the MCW could be limited by color vision deficiency (color blindness), but this problem only occurs in up to 8% of males and 0.5% of females [ 38].
