Sample screen colors with EyeDropper, convert HEX/RGB/HSL/CMYK, explore tints and shades, and calculate WCAG 2.1 contrast ratios in your browser.
Contrast: 2.54:1
Contrast: 8.28:1
Color choice impacts not only brand aesthetic but legal accessibility standards:
Ensure buttons, headings, and body copy meet legal ADA and European accessibility standards with AA/AAA ratings.
Export complete Tailwind CSS compatible tint/shade ramps (50 through 950) for your design system tokens.
Zero telemetry and zero cloud requests. All color sampling and transformations stay private in local RAM.
Our tool utilizes the modern W3C EyeDropper API built into Chromium and modern web browsers. When you click 'Pick from Screen', your cursor turns into a high-precision magnifying glass that samples the exact RGB pixel color from anywhere on your display, including outside the browser tab.
The Web Content Accessibility Guidelines (WCAG 2.1) require text to contrast sufficiently against its background. Level AA requires a minimum ratio of 4.5:1 for standard text (3:1 for large text). Level AAA requires an enhanced contrast ratio of 7.0:1 (4.5:1 for large text). Our calculator verifies compliance instantly.
Tints are generated by mathematically interpolating RGB values toward pure white (#ffffff, 255, 255, 255), creating lighter pastel variants. Shades are generated by interpolating toward pure black (#000000, 0, 0, 0), producing darker tones across a 10-step design scale.
RGB (Red, Green, Blue) is an additive color space used for illuminated digital screens and monitors. CMYK (Cyan, Magenta, Yellow, Key/Black) is a subtractive color model used in professional offset and commercial printing. Converting your RGB hex codes to CMYK ensures your brand colors print accurately on physical paper.
