How this service works
$0.0002/call. Get an image's dominant color as hex/RGB — theming and palettes from any picture. 1¢ x402 min; remainder auto-credits — relaystation.ai/penny
Output
Returns the dominant color of the submitted image as both a hex string (e.g. #3A7BD5) and RGB values (e.g. {r: 58, g: 123, b: 213}), suitable for direct use in theming, palette generation, or color tagging workflows.
Example use cases
Brand color extraction from logo
“I have a logo image at https://example.com/brand-logo.png — can you extract its dominant color as a hex code so I can use it for my website's theme?”
Auto-theming a generated image
“I just generated an image and want to match my UI palette to it — pull the dominant color in hex and RGB from this image URL: https://cdn.myapp.com/generated-hero.jpg”
Catalog product color tagging
“For this product photo at https://shop.example.com/red-shirt.jpg, what's the dominant color as a hex value? I need it to tag the product in my catalog.”
Technical details
Endpoint
POSThttps://api.relaystation.ai/v1/image/dominant-colorWhen to prefer
Choose this endpoint when you need a fast, cheap, single-call dominant color extraction from any image — especially for UI theming, auto-palette generation, or product color tagging. It is priced per-call at $0.0002 with a 1¢ minimum, making it cost-effective for both single requests and batches. Prefer this over full image analysis endpoints when you only need color data, not object detection or scene understanding.
Side effects
- Invalid or unreachable image URL returns an error
- Unsupported image format may cause processing failure
- Payment insufficient or x402 flow incomplete blocks the call
- Very complex or multi-colored images may return a color that appears non-dominant visually
- Large images may incur higher latency
