Pick colors from images, inspect HEX, RGB, and HSL values, check WCAG accessibility contrast, and generate color palettes.
The Color Picker is a complete color tool for web designers, developers, and artists. You can pick colors using an intuitive visual slider, extract exact pixel colors from uploaded photos with the eyedropper, inspect HEX, RGB, and HSL codes, and check accessibility contrast ratios.
Everything runs directly in your browser. Any photos or screenshots you upload to sample colors are processed strictly in local memory and are never uploaded to any server.
Designers test button background colors against white and dark text to ensure accessible contrast ratings.
Marketers extract exact hex codes from brand guidelines and packaging images for digital ad campaigns.
Developers copy color values in clean CSS formats (hex, rgb, hsl) directly into stylesheets.
Use the interactive color spectrum or upload an image and click any pixel to sample its color.
View the instant HEX, RGB, HSL, and HSV codes.

Verify if dark grey text (#4b5563) on a white background (#ffffff) is accessible.
WCAG guidelines require at least 4.5:1 for standard text and 3:1 for large text.
Solution: Make sure the image has finished loading into the preview box before clicking the eyedropper button.
MWT Labs tools are built using modern web primitives—including WebAssembly, Web Workers, and native HTML5 Canvas / Cryptography APIs. When you process images, parse PDF documents, format JSON payloads, or calculate financial schedules, execution happens strictly within your local browser memory sandbox.
The color picker supports HEX, RGB, HSL, and HSV color values with one-click copying for web design and CSS stylesheets.
Yes. You can upload any image or screenshot and use the interactive eyedropper cursor to sample the exact color of any pixel.
The contrast tool calculates the WCAG 2.1 contrast ratio between your chosen color and background colors, indicating whether the pair passes AA and AAA standards for readability.
Yes. It automatically generates complementary, analogous, triadic, and monochromatic color schemes based on your selected base color.
No. All image rendering and pixel sampling occur locally inside your browser's HTML5 canvas. Your images are never uploaded or saved anywhere.
Crop, rotate, and resize images with aspect ratio presets for social media and documents.
