While there has much published about color management and methods to achieve accurate color, little practical information has been published about test methods to verify or validate that color fidelity aims have indeed been achieved. This paper discusses why testing methods are important, describes a basic list of considerations for establishing test methods and finally details four practical color fidelity test methods.
