RGB vs. CMYK: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Published on November 21, 2024
RGB (Red, Green, Blue) is used for digital displays and emits light, while CMYK (Cyan, Magenta, Yellow, Key/Black) is for print and absorbs light.
Key Differences
RGB is a color model used for electronic displays, relying on light emission. CMYK, primarily used in printing, functions on light absorption and reflection.
RGB combines red, green, and blue light to create colors, ideal for screens and digital devices. CMYK uses cyan, magenta, yellow, and black inks to produce a wide range of colors for printing.
In RGB, when all colors are combined at their maximum intensity, it results in white. In CMYK, combining all colors typically produces a dark brown, thus black ink is used for depth and contrast.
RGB has a broader color range and can produce more vibrant colors than CMYK. CMYK, however, is calibrated for the physical limitations and requirements of printing.
Converting from RGB to CMYK can result in color shifts, as some RGB colors cannot be replicated with CMYK inks. This conversion is essential for accurate print reproduction.
