How this service works
The dominant colors of an image with their share of it, and its average color, as hex and RGB, for palettes, theming and search.
Output
A JSON object containing an array of dominant colors (each with hex string, RGB array, and share as a decimal fraction) and the overall average color as a hex string. For example: {"colors":[{"hex":"#2f2a22","rgb":[47,42,34],"share":0.31}],"average":"#7a6b55"}.
Example use cases
Auto-theming a product page
“I'm building a product page and want to auto-generate a color theme from the product image at https://store.example.com/product-hero.jpg — can you pull the top 3 dominant colors as hex codes so I can use them for the background and accent colors?”
Color-based image search indexing
“I need to index a batch of photos by their dominant colors for a visual search engine. Start with https://cdn.example.com/landscape.jpg — give me the top 5 colors with their hex, RGB, and what share of the image they take up.”
Brand palette verification
“Can you check what the dominant colors are in our logo image at https://brand.example.com/logo.png and tell me the average color too? I want to make sure it matches our brand palette of blues and whites.”
Technical details
Endpoint
GEThttps://7fg5bxb40m3f0v23.68r.lambda-web.us-east-1.on.aws/v1/colors?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured color data (hex, RGB, share) from a remote image URL for use in theming, palette generation, or color-based search indexing. It is purpose-built for color extraction and returns richer metadata (average color + per-color share) than generic image analysis APIs. Prefer it over general vision APIs when you specifically need color palette output without object detection or captioning.
Side effects
- Invalid or inaccessible image URL returns an error
- Image exceeds 20 MB or 40 megapixel limit
- Unsupported image format (only JPEG, PNG, WebP, AVIF, GIF, TIFF, SVG accepted)
- Count parameter outside 1-10 range causes validation error
- Network timeout fetching the remote image
- Payment failure or insufficient USDC balance blocks the request
