What is a Color Picker?
A color picker is a commonly used tool in frontend development and UI design that helps you precisely select colors and convert between different formats. HEX uses hexadecimal notation, RGB is based on red, green, and blue primaries, and HSL is based on hue, saturation, and lightness — each with its own use cases.
How to Use
- Click the color picker to select a color, or enter a color value in the input field
- View conversion results in HEX, RGB, and HSL formats
- Click the copy button next to a format to copy the color value
- Refer to color schemes for complementary, analogous, and other combination suggestions
- Check shades and tints for darker and lighter variants of the same color
Common Uses
- CSS Development: Quickly get HEX/RGB/HSL color values for style code
- UI Design: Select brand primary color and generate complete color schemes
- Accessibility Testing: Ensure sufficient contrast between text and background colors
- Color Conversion: Quickly convert between different color formats
FAQ
Q: What's the difference between HEX, RGB, and HSL?
A: HEX uses hexadecimal (e.g., #2563eb), common in CSS; RGB uses red, green, blue components (e.g., rgb(37,99,235)), good for programming; HSL uses hue/saturation/lightness (e.g., hsl(217,91%,53%)), more intuitive.
Q: What are complementary colors?
A: Complementary colors are opposite each other on the color wheel, like red and green, or blue and orange. Complementary color schemes create strong contrast and are often used for highlighting elements.
Q: How do I choose a good color scheme?
A: Analogous schemes are harmonious and natural, suitable for most cases; complementary schemes have strong contrast, good for emphasis; triadic schemes are vibrant, good for lively styles. A good ratio is 60% primary, 30% secondary, 10% accent.
Q: Will color data be uploaded to servers?
A: No. All color calculations happen locally in your browser. No data is ever uploaded.
