How it works
MulticolorEngine gives you the ability to search your images using colors as a search parameter. You are familiar with searching using keywords: you provide a keyword to a search engine and it replies with a list of search results that include that keyword. With MulticolorEngine, your search query is one or more colors and the results are images that contain your query colors.
MulticolorEngine starts by indexing all the images in your collection. The indexing process involves extracting detailed color information from each image in your image collection. The extracted color information is stored in our specialized MulticolorEngine color database. This indexing process facilitates fast searching based on colors and allows our MulticolorEngine to scale to searching hundreds of millions of images.
MulticolorEngine analyzes the pixels in the images and does not use meta data, tags or any other information associated with an image. It derives all the color data it needs from your images directly.
The MulticolorEngine color database can also maintain additional information about your images (e.g., tags and categories) and allow you to search based on this information in addition to colors.
MulticolorEngine is delivered as a fully-hosted web API. It runs over HTTP using a REST protocol and JSON or XML formatted responses. There is no software to install and maintain.

Can I see MulticolorEngine in action?
How does MulticolorEngine work?
The MulticolorEngine indexes all the images in your collection by extracting detailed color information about each one. This information is kept in a specialized color database that facilitates fast searching based on color. The colorDB can also maintain additional information about your images (e.g., tags and categories) and allow you to search based on this information.
What are the major functions supported by the API?
'remove'from the images in your collection of searchable images.
'search'for images that match one or more RGB colors - this is multicolor search.
'search'for images that match the colors of another image. This allows end users to find images that match the colors of their image.
'extract_colors'returns the dominant colors of a given image. This is very useful if a user wants to be able to search for images that match only some of the colors in an input image. You can show them the palette of their image and let them pick.
'extract_collection_colors'returns the colors of a subset of the images in your collection. This lets you show your users what colors you have, before they even start a color search.
'count_collection_colors'returns the number of your images that match a given color.
Will MulticolorEngine work with my images?
MulticolorEngine works with most images. But if you are concerned about your images or your particular use case scenario, please get in touch to describe your project in as much detail as possible, and we will provide an expert opinion. We are happy to work on challenging implementations!
How do I prepare my image collection for use with MulticolorEngine?
Images should be in JPEG, PNG or GIF format. They should be sized to approximately 200 pixels in the smallest dimension.
Where can I find documentation about the MulticolorEngine API?
Documentation for the MulticolorEngine API can be found here.
What programming languages are supported?
The API is independent of the programming language you use, so you can work with any language you like. We provide and support API libraries in many development languages in order to make it even easier to integrate. You can see our current library list here.
How does MulticolorEngine index my images?
Our MulticolorEngine extracts the colors from each image, and information about their prominence in it. That data is added to an index of all the colors of the images in your collection. When searches are performed, they start by looking up colors in the index.
How do I add my images to the MulticolorEngine API?
Images are submitted to the MulticolorEngine via an HTTP POST using the API‘s
'add' function. Submitted images are copied to our servers, where
their color information is extracted and stored in your color DB. That information is
used to find matches when searching by color. Images should be prepared as follows:
- JPEG, PNG, or GIF file types (not animated)
- Scaled to ~200 pixels in the SMALLEST dimension
Images that have not been scaled to 200 pixels will be scaled down automatically by the MulticolorEngine. However, large images increase transmission and processing time.
How are my images stored?
Your images are stored securely on our datacenter servers.
Can I integrate MulticolorEngine with other search functions?
Yes. We designed MulticolorEngine with this in mind. For example: keywords, metadata or categories.
