1. A method of sorting electronic color images of objects, the method comprising: receiving, at a server from an end-user device, an input representation of a desired object to be located in the color images, the input representation including first data representing a first color of the desired object, the first data being in a first color space, determining an indication of saturation of the first color; defining a prescribed range of saturation indications based on the determined indication of saturation of the first color; comparing the prescribed range of saturation indications to a plurality of candidate saturation indications associated with a plurality of stored candidate images; and in response to the candidate saturation indication associated with a presently compared one of the stored candidate images not being in the prescribed range of saturation indications, the prescribed range of saturation indications including the indication of saturation of the first color, discarding the presently compared candidate image as possibly including the desired object; or in response to the candidate saturation indication associated with the presently compared one of the stored candidate images being in the prescribed range of saturation indications, determining that the candidate image possibly includes the desired object.

The method of claim 1 further comprising: converting the first data in the first color space into second data in a second color space different than the first color space, wherein at least one of the first color space or the second color space includes a saturation parameter; determining a query feature vector including a plurality of parameters associated with color of the input representation, the query feature vector parameters including at least a first parameter from the first color space and at least a first parameter from the second color space; making a feature vector comparison by comparing the query feature vector to a plurality of candidate feature vectors associated with at least a portion of the stored candidate images, each candidate feature vector including a plurality of parameters associated with color of a respective one of the stored candidate images, the candidate feature vector parameters including at least the first parameter from the first color space and at least the first parameter from the second color space; and in response to the feature vector comparison, determining that the candidate image possibly includes the desired object.
