How this service works
Dominant colors of an image (URL or base64) with their share, in HEX and RGB, plus the average color and light/dark tone. For brand palettes, themes or tagging images by color.
Output
A JSON object containing: an array of dominant colors each with hex string, rgb array [R,G,B], and proporcion_pct (percentage share of the image); a color_medio object with the average image color in hex and rgb; and a tono field indicating 'claro' (light) or 'oscuro' (dark) overall tone.
Example use cases
Brand palette extraction from logo
“Here's our company logo image URL: https://mybrand.com/logo.png — can you pull out the top 6 dominant colors as HEX and RGB values so I can build our official brand color palette?”
Automatic dark/light theme detection
“I need to know if this banner image is predominantly light or dark so I can decide whether to overlay white or black text on it — can you analyze https://cdn.mysite.com/hero-banner.jpg and tell me the tone plus the average color?”
Color tagging for image library
“I'm cataloguing product images and need to tag them by color — analyze this base64 image and give me the top 4 dominant colors with their proportions so I can index it in our catalog.”

Endpoint
POSThttps://api.vextorium.com/paleta-imagen-pago?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically extract a structured color palette from any image — particularly for brand palette generation, UI theme derivation, or image cataloguing by color. It is well-suited for cases where you need both precise HEX/RGB values and proportional coverage data, plus a quick light/dark classification, without running a full ML pipeline locally.
Side effects
- Invalid or unreachable image URL returns an error

- colores parameter out of range (must be 2-16) may return error or default to 6
- Very small or uniform images may return fewer colors than requested
- Network timeout if the image URL is slow to load
- Payment not fulfilled returns HTTP 402
