Additive Colors vs. Subtractive Colors: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Updated on October 27, 2023
Additive colors combine light to create colors; subtractive colors mix pigments, absorbing light.
Key Differences
Additive colors refer to the system where colors are produced by mixing different hues of light, primarily red, green, and blue. When these primary lights combine, they form secondary colors. On the contrary, subtractive colors deal with the reflection and absorption of light by colored pigments or dyes. This system relies mainly on three primary colors: cyan, magenta, and yellow.
In the realm of additive colors, when you mix all primary light colors together (red, green, blue), the result is white light. This principle is the foundation for devices like televisions and computer screens. However, in the subtractive colors system, combining all primary colors (cyan, magenta, yellow) typically results in black or a muddy brown, since each color absorbs (subtracts) certain wavelengths of light.
Additive colors are named so because they "add" wavelengths of light to black, starting with no colors and achieving full brightness when all are combined. Devices that emit light, such as digital displays, utilize this principle. Conversely, subtractive colors work by "subtracting" brightness from white, meaning they remove certain wavelengths from light by absorbing them, as seen in paints and inks.
Human vision is inherently designed to perceive additive colors. Our eyes contain photoreceptors sensitive to red, green, or blue wavelengths, making the RGB system a natural fit for digital displays and lighting. In contrast, most physical media, like paper and fabrics, use subtractive colors since they don't emit light but rather reflect it. Mixing pigments in these media results in colors based on the parts of the light spectrum they reflect.
It's fascinating to observe the interplay between additive and subtractive color principles in daily life. For instance, a digital design on a screen (using additive colors) might appear differently when printed on paper (using subtractive colors). This distinction is crucial for professionals in fields like graphic design and photography to understand, ensuring consistency and accuracy in color representation across mediums.
