Frequently Asked Questions

What is a HEX color code?
A HEX color code is a 6-digit code representing red, green, and blue values in hexadecimal format. For example, #FF0000 represents pure red, #00FF00 is green, and #0000FF is blue. It may include an optional 2-digit alpha channel for transparency (e.g., #FF000080 for semi-transparent red).
What's the difference between RGB and HSL?
RGB (Red, Green, Blue) is additive color model used in digital displays. HSL (Hue, Saturation, Lightness) is more intuitive: Hue is the color (0-360°), Saturation is intensity (0-100%), and Lightness is brightness (0-100%). HSL is easier for creating color variations and harmonies.
How do I create accessible color combinations?
Use our contrast checker to ensure WCAG 2.1 compliance. For normal text, aim for a 4.5:1 contrast ratio. For large text, 3:1 is sufficient. Avoid red-green combinations for colorblind users and test with our color blindness simulator.
What are complementary and analogous colors?
Complementary colors are opposite on the color wheel (e.g., red and cyan) - they create high contrast. Analogous colors are adjacent (e.g., blue, blue-green, green) - they create harmonious designs. Our harmony analyzer helps generate these schemes automatically.
Can I save and export my color palettes?
Yes! You can save colors to history, generate palettes, and export them as CSS, SCSS, LESS, JSON, or plain text files. Share palettes via URL or download them for use in design tools like Figma, Adobe XD, or Sketch.
What is CMYK used for?
CMYK (Cyan, Magenta, Yellow, Black) is a subtractive color model used in printing. It represents the four ink plates in color printing. Our tool converts between CMYK for print and RGB/HEX for digital display.
How accurate is the color blindness simulation?
Our simulator uses established algorithms to approximate how colors appear to people with common types of color vision deficiency: Protanopia (red-blind), Deuteranopia (green-blind), and Tritanopia (blue-blind). This helps create accessible designs.
What are CSS custom properties (variables)?
CSS custom properties (--primary-color: #4f46e5) allow you to store color values for reuse throughout your CSS. Our tool generates CSS variables along with fallbacks for better maintainability and theming.
How do I create a gradient?
Use our gradient generator to create linear or radial gradients. Choose two or more colors, set direction/angle, and get instant CSS code. You can create multi-color gradients, repeating gradients, and gradient borders.
Is this tool completely free?
Yes! Our Hex Color Picker is 100% free with no limitations. All processing happens locally in your browser for privacy. No registration required - use it as much as you need for personal or commercial projects.

Color Theory & Professional Applications

Understanding color theory is essential for creating effective designs. Our tool implements professional color theory principles:

Color Models Explained

Different color models serve specific purposes in design and development:

  • HEX: #RRGGBB format used in web design (with optional alpha #RRGGBBAA)
  • RGB: Red(0-255), Green(0-255), Blue(0-255) for digital displays
  • HSL: Hue(0-360°), Saturation(0-100%), Lightness(0-100%) for intuitive adjustments
  • CMYK: Cyan, Magenta, Yellow, Black percentages for print design
  • HSV/HSB: Hue, Saturation, Value/Brightness similar to HSL but with different calculations
  • LAB: Perceptually uniform color space for color difference measurements

Advanced Color Harmony Types

Create professional color schemes using established harmony rules:

  • Complementary: Colors opposite on the color wheel - maximum contrast
  • Analogous: Colors adjacent on the wheel - harmonious and comfortable
  • Triadic: Three colors evenly spaced - vibrant and balanced
  • Split-Complementary: Base color plus two adjacent to its complement - less tension than complementary
  • Tetradic (Double Complementary): Two complementary pairs - rich but needs careful balancing
  • Monochromatic: Variations in lightness and saturation of a single hue - cohesive and elegant
  • Square: Four colors evenly spaced - balanced with variety

Accessibility & Inclusive Design

Creating accessible color schemes is crucial for inclusive design:

  • WCAG 2.1 Compliance: Ensure sufficient contrast ratios for text and UI elements
  • Color Blindness Considerations: 8% of men and 0.5% of women have color vision deficiency
  • Perceptual Uniformity: Use LAB color space for accurate color difference calculations
  • Cultural Considerations: Colors have different meanings across cultures
  • Dark Mode Support: Test colors in both light and dark themes

Professional Workflow Integration

Our tool integrates seamlessly with professional design and development workflows:

  • CSS Preprocessor Support: Export to SCSS, LESS, or Stylus variables
  • Design Tool Compatibility: Generate palettes compatible with Figma, Adobe XD, Sketch
  • Version Control Friendly: Export color systems as JSON for team collaboration
