What colors make black involves a different process than mixing other colors. In the world of additive color theory, where colors are created by combining light, black is the absence of color. In subtractive color theory, which deals with pigments, you can achieve black by mixing complementary colors.

Primary Colors:

Combining primary colors in equal parts doesn't create black but rather a shade of brown or gray.

Complementary Colors:

In subtractive color mixing, combining complementary colors, like red and green or blue and orange, can result in a form of black, depending on the intensity and proportions.

CMYK Model:

In printing, black is often achieved using the CMYK color model by combining cyan, magenta, yellow, and key (black) inks.

Remember, achieving a true and deep black may require experimentation and adjustment of color proportions. Understanding the color wheel and experimenting with different color combinations will enhance your ability to create various shades, including black.
