Dominant colors

Sirv can identify the dominant color in each of 64 parts of your image. Each area is divided equally by height and width, like these examples:

Division of image into 8×8 grid for dominant colors
Division of image into 8×8 grid for dominant colors
Division of image into 8×8 grid for dominant colors

Obtain the 64 dominant colors in either JSON or JSONP format by appending ?histogram=rgb&info to your image.

JSON example:

https://demo.sirv.com/example.jpg?histogram=rgb&info

JSONP example:

https://demo.sirv.com/example.jpg?histogram=rgb&callback=abc

Values for the 64 areas are displayed in sets of 8, like so:
