Common Use Cases
Web Design & UI Development
Pick exact hex color codes for CSS, check text-to-background contrast ratios for WCAG AA/AAA compliance, and generate complete color palettes from a single brand color using our palette generator.
Brand Identity & Graphic Design
Extract the dominant brand colors from a logo or product image, build harmonious color schemes using complementary and triadic color relationships, and convert brand colors between HEX, RGB, and HSL formats.
Accessibility Auditing
Check that every color combination on your website meets WCAG 2.1 contrast requirements for users with low vision. Our Contrast Checker shows pass/fail status for both AA and AAA levels.
Tips & Best Practices
- WCAG AA requires a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text (18pt+). Our Contrast Checker shows both thresholds simultaneously.
- When extracting a color palette from a logo, use a PNG version with a transparent background for cleaner color extraction results.
- CSS custom properties (CSS variables) are the best way to apply your color palette — generate them from our Color Palette tool and paste directly into your :root{} block.
- HSL values are more intuitive for adjusting colors programmatically — increase L (lightness) to create hover states and tints, decrease for shades.

Frequently Asked Questions
How do I find the hex color code of any color on my screen for free?
Use our Color Picker tool. It provides an interactive color wheel and spectrum slider to select any color and instantly shows its HEX, RGB, HSL, and CMYK values.
How do I extract a color palette from an image for free?
Use our Image Color Picker or Color Palette Generator. Upload your image and it extracts the dominant colors using the Canvas API — your image never leaves your browser.
How do I check if my website colors meet WCAG accessibility standards?
Use our Contrast Checker tool. Enter your text color and background color, and it calculates the contrast ratio and shows whether it passes WCAG AA (4.5:1) and AAA (7:1) standards.
How do I convert HEX color codes to RGB or HSL?
Our RGB to HEX Converter handles bidirectional conversion. Enter a HEX code and get RGB and HSL values, or enter RGB values and get the equivalent HEX code.
How do I generate a harmonious color palette for my website?
Use our Color Palette Generator. Input a base color and it generates complementary, triadic, analogous, and split-complementary color schemes with HEX and RGB codes.
What is the difference between HEX, RGB, and HSL color formats?
HEX is the most common format for web CSS (e.g., #FF5733). RGB defines colors by Red, Green, Blue intensity values (0–255). HSL defines colors by Hue, Saturation, and Lightness — most intuitive for making color variations programmatically.
Can I check WCAG color contrast for my entire design system?
Yes. Use our Contrast Checker with each text/background color pair in your design system. The tool shows the exact contrast ratio and pass/fail status for AA and AAA at both normal and large text sizes.
