The Opposite of Red in RYB, RGB, and CMYK Color Models

The opposite of red on the color wheel is green. In the traditional RYB (red, yellow, blue) color model, red and green are considered complementary colors, meaning they are opposite each other on the color wheel and create the strongest contrast when placed side-by-side.

However, it’s important to note that there are different color models, and the exact opposite of red can vary depending on the model being used:

RGB (red, green, blue) color model: In this additive color model, used primarily for digital displays, the opposite of red is cyan, which is a combination of green and blue light.

CMYK (cyan, magenta, yellow, key/black) color model: In this subtractive color model, used mainly for printing, the opposite of red is green, as in the RYB model.

In terms of color perception, the opposite of red is often considered to be a bluish-green color, as these colors are on opposite sides of the color spectrum and create the greatest visual contrast.
