What do you do to the colors in the background make it look farther away?

To create the illusion of depth and make background colors appear farther away, use lighter and less saturated hues. This technique, known as atmospheric perspective, mimics how colors fade and lose intensity with distance. Additionally, incorporating a gradual shift in color temperature, such as cooler tones in the background, can enhance the sense of depth. These adjustments help to create a more realistic and three-dimensional effect in artwork.
