Key Differences
RGB (Red, Green, Blue) is a color model primarily used in electronic displays like TVs, computers, and smartphones. It's based on light emission, mixing these three colors at various intensities to produce a wide range of colors. Conversely, CMYK (Cyan, Magenta, Yellow, Key/Black) is a subtractive color model used in color printing. It blends these four ink colors to produce a broad spectrum of colors.
RGB is additive; combining all colors at their highest intensity produces white. In this model, colors are added to black (the absence of light) to create new colors. In contrast, CMYK is subtractive; combining all ink colors in theory results in black, but in practice, it produces a muddy brown, hence the need for the key (black) component.
When designing for digital screens, RGB is used because it offers a wider range of vibrant colors suitable for screens that emit light. However, for printing materials like brochures or magazines, CMYK is the standard because it reflects how inks absorb and reflect light on paper.
RGB colors can appear differently on various devices due to differences in display technology and settings. On the other hand, CMYK provides more consistent color output in the physical print, though it has a smaller color gamut compared to RGB.
In the digital realm, RGB is often used because of its ability to produce bright and varied colors. Conversely, CMYK is essential in printing because it aligns with the color blending process of printers and is vital for accurate color reproduction in print materials.

Common Curiosities
When should I use RGB?
Use RGB for anything displayed on digital screens, like websites and videos.
When is CMYK preferred?
CMYK is preferred for printed materials like brochures and business cards.
What does RGB stand for?
RGB stands for Red, Green, and Blue.
Are RGB colors consistent across devices?
No, RGB colors can vary due to different display technologies and settings.
What does CMYK stand for?
CMYK stands for Cyan, Magenta, Yellow, and Key (Black).
Can I use CMYK for web design?
No, web design should be done in RGB for accurate color display on screens.
Can RGB display more colors than CMYK?
Yes, RGB has a wider color gamut and can display more vibrant colors.
Why can't I use RGB for printing?
RGB is designed for light-based displays and does not translate well to ink-based printing.
How do RGB and CMYK affect design?
Designers must consider the final medium (screen or print) to choose the right color model.
Can I convert RGB to CMYK?
Yes, but the conversion may alter some colors due to the different gamuts.
Do printers print RGB directly?
Most standard printers are calibrated for CMYK, not RGB.
Why do printed colors sometimes look different from the screen?
This is due to the difference between light-based RGB colors on screens and ink-based CMYK colors in print.
Does CMYK cover the same range of colors as RGB?
No, CMYK has a narrower color range compared to RGB.
Why does black in CMYK look different than in RGB?
In RGB, black is the absence of light, while in CMYK, it's a combination of inks.
Is CMYK suitable for digital artwork?
No, CMYK is best for print work; digital artwork is better in RGB.
