1. A color retrieval neural network for retrieving standards from a database of standards based upon color values of a sample, said color retrieval neural network comprising:

  • an input layer having input nodes for receiving input data related to the color values of the sample;

    an output layer having output nodes for providing output data related to the standards in the database;

    first weighted connections connected to said nodes of said input layer, each of said first weighted connections having a coefficient for weighting said input data; and

    wherein a non-linear relationship exists between said input data to the input layer and output data from the output layer, the database including color values associated with a plurality of angles for each standard in the database, said non-linear relationship interrelating color values of the sample at different angles with the color values associated with the different angles of at least one of the standards in the database.
