What do you do to the colors in the backround of a picture to make it look farther away?

To create the illusion of distance in a picture, you can desaturate the colors in the background, making them less vibrant. Additionally, using lighter tones and incorporating a slight blur can enhance this effect. Atmospheric perspective techniques, such as adding a blue or gray tint, can also help simulate depth by mimicking how colors appear in the distance due to atmospheric conditions.
