Frequently Asked Questions

A HEX color code is a 6-character hexadecimal representation of a color, commonly used in web design. It consists of three pairs of characters representing Red, Green, and Blue values (00-FF). For example, #FF0000 is pure red.

To convert HEX to RGB, split the 6-character code into three pairs and convert each from hexadecimal to decimal. For example, #FF5733 becomes RGB(255, 87, 51): FF = 255, 57 = 87, 33 = 51.

RGB represents colors as combinations of Red, Green, and Blue light values (0-255 each). HSL represents colors using Hue (0-360°), Saturation (0-100%), and Lightness (0-100%). HSL is more intuitive for creating color variations.

Color contrast ensures that text and interactive elements are readable by people with visual impairments, including color blindness and low vision. WCAG guidelines require a minimum contrast ratio of 4.5:1 for normal text.

Start with colors that meet WCAG AA contrast requirements (4.5:1 for text). Test your palette with contrast checkers, consider color blindness simulation, and ensure you don't rely solely on color to convey meaning.

HEX and RGB are most widely supported. HSL is excellent for creating variations and theme systems. OKLCH is the modern choice for perceptually uniform colors and is supported in all modern browsers.

Use an image color picker tool that lets you upload an image and click on any pixel to extract its color code. Our tool processes images locally in your browser for privacy.

Complementary colors are pairs of colors that are opposite each other on the color wheel, such as red and green, or blue and orange. They create strong visual contrast and are useful for highlighting important elements.
