How Colors Make Things Look Close or Far Away
Welcome to Colors!
Colors are really important on the computer screen. They can make things look closer or farther away. In this study, we'll learn about how different colors can make things look like they're coming towards us or going away. We'll even try to make a guess about how far things are based on their color!
Advancing and Receding Colors
Advancing and receding colors are essential for creating the perceived depth needed for GUI design. Recent studies challenge the belief that color advancing and receding are solely a result of training and association, suggesting that they stem from color sensation.
Chromostereopsis and Color Perception
Chromostereopsis experiments have shown that red colors appear closer than blue colors on the same surface. The wavelength of a color influences its perceived depth, with longer wavelengths being more advancing and shorter wavelengths being more receding.
Objective
This study aims to comprehensively understand the phenomenon of perceived color depth and develop a best-fit model for predicting it based on CIELAB color attributes. Color pairs were used in an experiment to observe depth perception caused by colors and obtain judgments of color depth perception.
Experimental Method
In the experiment, 32 colors within the boundary of basic color terms and their variations were used. Observers... [Add more details about the experimental method]
Color Perception and Depth
The perceived depth of colors is determined by the number of times they are observed. Colors with a larger score are seen as receding, while those with a smaller score are seen as advancing. Factors such as chroma, lightness, and hue angle influence the perceived color depth.
Order of Color Perception
Colors with lower chroma and lightness are perceived as farther away, while lighter and more colorful colors are seen as closer. Hue angle also plays a role, with yellowish and reddish hues tending to advance and bluish and greenish hues tending to recede.
Correlation with Color Attributes
Lightness and chroma are negatively correlated with perceived color depth, meaning that higher lightness and chroma result in a closer perception. On the other hand, lower lightness and chroma lead to a perception of greater distance. Hue angle follows a negative sine function curve, with bluish colors tending to recede and purplish, reddish, and yellowish colors tending to advance.
Warm/Cool Colors and Perceived Depth
The perception of warm/cool colors does not align with perceived color depth. Although the correlation between warm/cool emotion and perceived color depth is moderate, the model of color heat, which considers chroma and hue, enhances the effect of hue angle on color heat. Perceived color depth is influenced by lightness, chroma, and hue angle simultaneously.
Practical Applications in GUI Design
This study aims to provide insights into color-induced depth perception for practical application in GUI design. The best-fit regression model, based on device-independent color attributes (CIELAB), reveals that lightness, chroma, and hue angle all affect the perceived color depth. These findings can inform the design of visually pleasing and engaging interfaces.
