What is a Color Picker?
A color picker is an essential tool for designers, developers, and digital creators that allows you to select, analyze, and convert colors between different formats. This free online color picker provides instant conversion between HEX, RGB, HSL, HSV, and CMYK color spaces, making it easy to work with colors across different design tools and platforms.
Beyond basic color selection, this tool includes an accessibility contrast checker that verifies your color combinations meet WCAG (Web Content Accessibility Guidelines) standards. Ensuring proper contrast ratios is crucial for creating inclusive designs that everyone can read and interact with, including people with visual impairments.
The eyedropper feature lets you pick any color directly from your screen - perfect for matching colors from images, websites, or other applications. All color values are instantly available in multiple formats with one-click copying to your clipboard.
Understanding Color Formats
HEX Colors
Hexadecimal color codes (#RRGGBB) are the web standard. Each pair represents red, green, and blue values from 00-FF. Perfect for CSS and HTML.
RGB Colors
RGB uses red, green, blue values from 0-255. It's how monitors display color and is commonly used in CSS with rgb(R, G, B) syntax.
HSL Colors
Hue (0-360°), Saturation (0-100%), Lightness (0-100%). More intuitive for humans - adjust lightness without changing the color's character.
HSV/HSB Colors
Hue, Saturation, Value (Brightness). Popular in design tools like Photoshop. Value at 100% gives the purest form of the color.
CMYK Colors
Cyan, Magenta, Yellow, Key (Black). Used for print design. Note: screen previews are approximations since CMYK is a subtractive color model.
Color Accessibility
WCAG AA requires 4.5:1 contrast for normal text, 3:1 for large text. AAA requires 7:1 and 4.5:1 respectively. Essential for inclusive design.
Common Use Cases
Web Development
Convert colors between formats for CSS, ensure brand colors are consistent across your codebase, and verify text/background combinations pass accessibility checks.
UI/UX Design
Create color palettes with shades and tints, match colors from inspiration images, and ensure designs are accessible to users with vision impairments.
Brand Design
Get precise color values from existing brand assets, create style guides with all color formats, and generate consistent shade variations.
Print Preparation
Convert screen colors to CMYK approximations for print design. Note that actual print colors may vary - always proof with your print provider.
