Color Picker from Image
Picks colors directly from an uploaded image by sampling pixel data on a canvas, returning the hex, RGB, and HSL values at the cursor position with a magnified loupe view, useful for matching brand colors from screenshots, building design palettes from product photos, and identifying dominant colors when no design file is available..
Color Name Finder
Finds the closest standard CSS named colors (like IndianRed or SteelBlue) to any hex color, ranked by color distance..

Calculates the WCAG contrast ratio between a text and background color and checks it against AA and AAA accessibility thresholds, with a live text preview..
Color Blindness Simulator
Simulates how colors appear to viewers with deuteranopia, protanopia, tritanopia, and achromatopsia by applying dichromacy approximation matrices to a color or gradient, with side-by-side before/after preview.
Aspect Ratio Calculator
Simplifies any width × height into a clean w:h ratio (e.g. 1920×1080 → 16:9) with its decimal value and detects common preset matches, and computes the missing dimension when you know the ratio and one side.
Converting between color formats
The Color Converter translates between hex, RGB, HSL and named colors so you can paste values between design and code.
Use RGB to Hex or Hex to RGB for quick one-off conversions.
Accessibility and palettes
The Contrast Checker reports WCAG ratios for text/background pairs to ensure accessible designs.
Generate harmonious palettes from a base color, and sample real colors from an uploaded image with the Color Picker.
