How Canvas Palette Extraction Works
When you select an image, this utility draws the graphic data onto an invisible HTML5 canvas element. The browser reads the individual RGBA parameters of each pixel to isolate, cluster, and rank the most frequently occurring hex color values.
Data Security:
No files are uploaded to an external server or API. The image is processed entirely inside your browser's local memory, making this utility safe for processing sensitive graphics or private wireframes.
Extracted values are output in standard hexadecimal format, allowing for direct copy-pasting into CSS, Figma, Tailwind, or other design environments.
