Abstract: In one example, a color reference chart for evaluating a chrominance signal of a video image includes a plurality of color samples arranged in an array, wherein the plurality of color samples comprises: a first color sample of a first known, non-neutral hue and saturation and a second color sample of a second known, non-neutral hue and saturation positioned so that at least a portion of the second color sample is directly adjacent to at least a portion of the first color sample, and a barrier of a known neutral color positioned directly adjacent to the plurality of color samples without separating the at least a portion of the second color sample from the at least a portion of the first color sample.
