Frequently Asked Questions
What is the difference between HEX, RGB, HSL, and HSV color formats?
HEX uses a six-digit hexadecimal code (like #FF5733) to represent colors, commonly used in web design and CSS. RGB defines colors using three numbers from 0-255 for red, green, and blue channels. HSL (Hue, Saturation, Lightness) separates the color hue from its intensity, making it more intuitive for designers. HSV (Hue, Saturation, Value) is similar to HSL but uses Value instead of Lightness, which some designers prefer for selecting vivid colors.
How do I check if my text and background colors meet accessibility standards?
Our color picker includes a built-in WCAG contrast checker that calculates the contrast ratio between your selected color and both white and black text. According to WCAG 2.1 guidelines, normal text requires a minimum contrast ratio of 4.5:1 for AA compliance and 7:1 for AAA compliance. Large text (18pt or 14pt bold) needs at least 3:1 for AA compliance. The tool displays pass or fail badges for each standard.
What are color harmonies and how do I use them?
Color harmonies are combinations of colors that look visually pleasing together, based on their positions on the color wheel. Complementary colors sit opposite each other and create high contrast. Analogous colors are adjacent and create a harmonious, cohesive look. Triadic colors are evenly spaced around the wheel for a vibrant palette. Split-complementary uses a base color plus the two colors adjacent to its complement. Click any harmony swatch to copy the HEX code.
