Table 4: Multi-factor regression models of color element differences with eye-tracking metrics and subjective comfort. as pleasure and happiness [55]. As a result, visual preference for color combinations in the orange and yellow hues was significantly higher than that for the red group. As hues transition from warm to cool, users' emotions shift from high activity to low activity. Purple, as a transitional color between warm and cool tones, exhibited the highest FC value.
