Pick exact image pixels, extract a color palette, copy HEX, RGB or HSL, and check WCAG text contrast.
Get started
Choose an image and select a pixel, or use the coordinate fields and arrow keys.
Select palette colors and compare foreground and background contrast.
Copy color values or export the palette as CSS or JSON.
Know the limits
JPG, PNG and WebP up to 20 MB / 16 MP. Palette extraction uses a 256-pixel sample and may return fewer distinct colors. Transparent pixels are composited onto white. WCAG ratios apply to solid color pairs, not every background or font.
