The color of a computer screen is determined by the light emitted from the backlight and the color filter. The type of color mixing used on a computer screen depends on how the backlight and filter are combined to create an image. There are three types of color mixing: additive, subtractive, and grayscale.

The Different Types of Color Mixing
Three primary colors are red, yellow, and blue (RGB). These colors cannot be made by mixing other colors. Instead, all other colors are created by combining these primary colors in different combinations and proportions.
The three types of color mixing are additive, subtractive, and computer screens. Additive color mixing is used when light is projected onto a surface. For example, red and green make yellow, green and blue make cyan, blue and red make magenta, and all three together make white.
Subtractive color mixing is used when colorants are added to a substrate. The three subtractive primary colors are cyan (C), magenta (M), and yellow (Y). Cyan absorbs red light, magenta absorbs green light, and yellow absorbs blue light. These three colorants can be combined in various proportions to produce a wide array of different colors.
Computer screens use a combination of both additive and subtractive color mixing to create the colors that you see on your screen. Cyan (C), magenta (M), and yellow (Y) colored filters are placed over the pixels on the net. This combination of RGB light and CMY filters produces the vast array of colors you see on your computer screen.
How do Computer Screens Use Color Mixing?
Different colors of light can be combined in two different ways. The first is called additive mixing and stuffed the mixing we see on computer screens. The colors of the pixels on the screen are produced by red, green, and blue light-emitting diodes (LEDs). We can create any color we want by varying the intensity of these colors.
The second type of color mixing is called subtractive mixing. This is the mixing that we see in print. In subtractive mixing, different ink colors are combined to create new colors. For example, if you print a yellow circle on paper, the ink will absorb all other stains except yellow. This will cause the eye to see only yellow.
Subtractive mixing is also how color is produced in paintings and photographs. In an image, different shades of paint are mixed to create new colors. Likewise, other light colors are filtered in a picture before they reach the film or sensor. This is why you need a red filter to take black and white images through green foliage – the red filter absorbs green light, leaving only red and blue light to reach the film or sensor.
The Benefits of Using Color Mixing
Additive color mixing is used by computer screens, televisions, and other electronic devices, while subtractive color mixing is used in printing. Although both types have their benefits, additive color mixing is generally considered superior because it can create a broader range of colors.
Additive color mixing occurs when different light colors are combined to create a new color. For example, if you mix red and green light, you will get a yellow light. When all three primary colors (red, green, and blue) are combined in equal proportions, you get white light. In contrast, subtractive color mixing occurs when different pigment colors are combined. For example, if you mix yellow and blue paint, you will get green paint.
