Color models and color spaces describe how colors are represented and used in digital and print workflows. RGB and CMYK are common color models, while color spaces such as sRGB, Display P3, CIELAB, LCH, OKLab, and OKLCH provide different ways to represent colors.
CMYK
- CMYK stands for Cyan, Magenta, Yellow, and Key (Black). It's a color model used in printing.
- Printers mix these four ink colors to create a wide range of other colors.
- Each letter in CMYK represents one of the main colors used. Cyan is a shade of blue, Magenta is a shade of pink, Yellow is the yellow ink, and Key refers to the black ink used to add depth and detail.
- By combining different amounts of these inks, printers can produce vibrant and accurate colors on paper.
RGB
- RGB stands for Red, Green, and Blue. It is a color model used for digital screens like TVs, computers, and smartphones.
- In the RGB model, colors are created by mixing different amounts of red, green, and blue light.
- When combined in various ways, these three colors can produce millions of different colors.
- RGB is essential for displaying images and graphics on digital devices, making it a key concept in digital design and photography.
sRGB
- sRGB is a standard RGB color space widely used for digital content.
- It is supported by most web browsers, displays, and digital devices.
- It provides a common color range that helps colors appear more consistently across different devices.
Display P3
- Display P3 is a wide-gamut color space that can represent a wider range of colors than sRGB.
- It is commonly used for modern digital displays and design workflows.
- Display P3 can represent colors that may not be available in the standard sRGB color space.
CIELAB (Lab)
- CIELAB, also called Lab, is a color space designed to represent colors based on human color perception.
- It uses three components: Lightness (L), and two color components called a and b.
- Lab is commonly used for color comparison, conversion, and color management.
LCH
- LCH is a color space based on Lab that represents colors using Lightness, Chroma, and Hue.
- It provides a way to adjust the lightness, color intensity, and hue of a color.
- LCH is used in modern digital color workflows and color design.
OKLab
- OKLab is a perceptual color space designed to represent colors and their differences more consistently.
- It uses Lightness and two color components called a and b.
- OKLab is useful for creating and adjusting digital color palettes.
OKLCH
- OKLCH is a cylindrical version of OKLab that represents colors using Lightness, Chroma, and Hue.
- It makes it easier to adjust a color's lightness, intensity, and hue.
- OKLCH is used in modern web and digital color workflows.
