About Color & Design Tools
Web color hex codes are the reason many people encounter hexadecimal at all. This category converts hex color codes to and from RGB, HSL, and CMYK — the formats used constantly in CSS, design tools, and print workflows.
Frequently Asked Questions
Why do CSS colors use hex instead of decimal?
A 6-digit hex code packs the red, green, and blue channels (0-255 each) into a compact, copy-pasteable string — #2563EB instead of rgb(37, 99, 235).
Is HSL or RGB more useful for design work?
RGB matches how screens render color channels. HSL separates hue from saturation and lightness, which makes it easier to create consistent color variations by hand.
