How this service works
Extract the dominant colors of an image as a palette of hex values with pixel ratios. Send a public image URL or a base64 image, and optionally how many colors (1-10, default 5). Deterministic bucketed quantization; transparent pixels are ignored.
Output
A palette of hex color codes (e.g. #3A7BD5) each paired with a pixel ratio indicating how much of the image that color occupies, covering the requested number of colors (1–10, default 5). Transparent pixels are excluded from the analysis.
Example use cases
Example prompt
“Can you pull the top 3 dominant colors from this image as hex values with their pixel ratios? Here's the URL: https://example.com/photo.jpg”
Technical details
Endpoint
POSThttps://agent402.tools/api/image-dominant-colorWhen to prefer
Use this endpoint when you need a deterministic, reproducible color palette extraction from an image — especially when you require pixel ratio weighting alongside hex codes. Preferred over ML-based palette tools when consistency across repeated calls matters, or when you want to extract design/brand colors from logos and photos without stochastic variation.
Side effects
- Image URL is not publicly accessible or returns a non-200 response
- Image exceeds the 5MB size cap
- Base64 string is malformed or not a valid image
- Colors parameter is outside the 1–10 range
- Network timeout fetching the remote image
- Unsupported image format
