Palette Grab

Palette Grab pulls the real color palette out of whatever is on your screen. Click the icon and it reads the visible part of the current tab, quantizes it, and hands you the dominant colors with their hex, RGB and HSL values — plus how much of the screen each one actually covers. WHAT MAKES THE COLORS RIGHT Most color pickers count pixels and hand back mud. A photograph contains thousands of near-identical values, so "most common RGB" returns six versions of the same grey. Palette Grab runs a median-cut quantizer instead: it subdivides color space rather than counting values, so every color it returns represents a genuinely distinct region of the image. Gradients, photography and video frames all come back with a usable palette. WHAT YOU GET • 3 to 10 colors, adjustable live — no re-capture needed • Hex, RGB, HSL and dominance share for every color • A toggle to skip near-white, near-black and grey, which otherwise dominate any screenshot and are rarely what you came for • Click any swatch to copy its hex; the label stays readable because the text color is contrast-checked against the swatch itself • Recapture after scrolling to sample a different part of the page EXPORTS • Hex — a plain list • CSS — a :root block of custom properties, numbered or named by hue (--color-blue, --color-sand) • Tailwind — a valid tailwind.config.js theme.extend.colors object • JSON — an array with hex, rgb, hsl and share • SVG — a proportional palette strip you can drop into Figma or a README WORKS ON REAL PAGES Palette Grab reads a capture of the tab, not the page's image elements. That matters: pulling a cross-origin image into a canvas taints it and reading the pixels back throws a security error, which is why so many color-picker extensions quietly fail on the sites you actually want to sample. This approach works on any normal page, including cross-origin photography, embedded video frames and canvas.
