What is the difference between RGB and CMYK?

RGB and CMYK are two different color models used in the world of digital and print graphics, each serving specific purposes. Here are the key differences between RGB and CMYK:

RGB (Red, Green, Blue):

Additive Color Model: RGB is an additive color model, which means colors are created by adding different amounts of red, green, and blue light. Combining all three at full intensity results in white light.

Digital Display: RGB is primarily used for digital displays, such as computer screens, television monitors, and smartphone screens. These devices emit light to create colors, and RGB is well-suited for this purpose.

Color Range: RGB has a wide color gamut and can produce a broad spectrum of colors, including vibrant and saturated colors. It is ideal for displaying colorful graphics and images on screens.

Primary Colors: The primary colors in the RGB model are red, green, and blue.

Hexadecimal Representation: RGB colors are often represented in hexadecimal notation, with values ranging from 0 to 255 for each of the three channels. For example, pure red is (255, 0, 0).

Examples of Use: Digital art, web design, photo editing, video games, and any content displayed on screens use the RGB color model.

CMYK (Cyan, Magenta, Yellow, Key/Black):

Subtractive Color Model: CMYK is a subtractive color model used in the printing industry. It works by subtracting varying percentages of cyan, magenta, yellow, and black ink from a white background to produce colors.

Printed Materials: CMYK is the standard color model for producing printed materials, such as brochures, posters, magazines, and packaging. It is used because printed materials do not emit light but rely on reflecting and absorbing light.

Color Range: CMYK has a more limited color gamut compared to RGB. It is often unable to reproduce the same level of vibrancy and brightness as RGB colors.

Primary Colors: The primary colors in the CMYK model are cyan, magenta, yellow, and black. Black is added because the subtractive process doesn't always produce a true black, and adding black helps achieve darker tones.

Percentage Values: CMYK colors are represented in percentage values, with 0% indicating no ink and 100% indicating full ink coverage. For example, pure red can be represented as (0%, 100%, 100%, 0%).

Examples of Use: Anything that will be printed on physical media, including posters, brochures, business cards, and packaging, is typically designed using the CMYK color model.

In summary, RGB is used for digital displays and is additive, creating colors by adding light. CMYK is used for printed materials and is subtractive, creating colors by subtracting ink from a white background. Understanding the difference between these two color models is crucial for ensuring that digital designs intended for print will appear as expected and that colors will be accurately reproduced in both mediums.
