Frequently Asked Questions

Color conversion is the process of translating one color format into another, such as HEX to RGB or HSL. It is necessary because different tools and platforms use different color formats.
HEX is a hexadecimal color notation (#FF6600), commonly used in web development. RGB defines color through three channels — red, green, and blue (0-255). HSL describes color using hue, saturation, and lightness, which makes it easier to adjust shades.
When transferring colors from a design mockup to code, when working with different design tools, or when you need to fine-tune a shade using HSL instead of editing RGB values directly.
CMYK is a color model used for printing that combines four inks: cyan, magenta, yellow, and black. Unlike RGB, which works with light on screens, CMYK describes ink mixing on paper.
