When you look at your phone, computer, or TV screen, you’re actually seeing thousands—sometimes millions—of tiny lights working together. These lights blend red, green, and blue to create the full spectrum of colors your eyes perceive. This system is known as RGB, an abbreviation for Red, Green, Blue.
Why Is RGB So Common?
RGB is aligned with how the human eye works. Our retinas contain light-sensitive cells that respond primarily to red, green, and blue wavelengths. Screens mimic this biological system to display colors in a way that feels natural to us.
How Do You Use RGB Color?
RGB color is best suited for on-screen applications, such as graphic design. Each color channel is expressed from 0 (least saturated) to 255 (most saturated). This means that 16,777,216 different colors can be represented in the RGB color space.
Advantages of RGB Color
Almost every well-known application is compatible with RGB, such as Microsoft Office, Adobe Creative Suite (InDesign, Photoshop, etc.), and other digital editors.
