What Are CMYK and RGB, and How Are They Different?
Many people have faced this problem: Why do the colors on screen look different from the printed version?
The main reason lies in the color systems (Color Modes) used for design and printing theyre not the same.
Globally, there are two primary systems: RGB and CMYK.
Lets break down what each one is, how they work, and when to use them.
What Is RGB? Colors for Screens and Digital Devices
RGB stands for Red, Green, Blue.
Its the color system used for light-emitting devices such as computer monitors, phones, TVs, and digital cameras.
RGB works on an Additive Color model it creates color by mixing light.
The more light you add, the brighter the color becomes.
Red + Green + Blue = White
No light = Black
Best for: Websites, social media posts, digital images, videos
Highlights: Bright, vivid, and glowing colors because screens emit light directly.
What Is CMYK? Colors for Real-World Printing
CMYK stands for Cyan, Magenta, Yellow, and Key (Black).
Its the color system used in printers and printed materials such as business cards, brochures, books, packaging boxes, and posters.
CMYK uses a Subtractive Color model it creates color by layering ink.
Each ink color absorbs (or filters) light on paper.
As more inks are layered, the color becomes darker.
In theory, C + M + Y = black, but in practice it turns brownish, so K (Black) is added to produce a deeper black.
Best for: Business cards, posters, menus, flyers, product boxes
Highlights: Accurate and consistent color results for all real-world print production.
Why Do Screen Colors Look Different from Printed Colors?
Because screens use RGB (light), while printers use CMYK (ink).
When colors are converted from light to ink, they may shift or appear duller especially bright tones like neon blues or greens.
How to fix it:
Set your design file to CMYK mode before sending it to print
Use a color-calibrated monitor
Request a color proof from your printer before final production
In Short
RGB = Colors from light for screens
CMYK = Colors from ink for print
