Paper Abstract

The range of color spaces for possible use with digital photography presents challenges and opportunities for engineers, developers and users of digital cameras. This paper will provide an overview and comparison of a sub-set of these color spaces, with specific consideration for digital photography. Primarily the RGB or red, green and blue color spaces will be compared and although other spaces, such as CIELAB and Yu’v’, will be mentioned. Background will be provided with respect to key considerations for design and use of color spaces for digital photography. Data will be presented on color space uniformity using a radial sampling of the OSA Uniform Color Scales and tritanopic confusion lines. In addition, color difference statistics across a fixed sampling will be used to assess the similarity of color spaces and to quantify the resulting error when color spaces are incorrectly assigned. Finally, the gamut shapes will be compared using procrustes analysis of a set of gamut landmark colors. The resulting dendrogram provides a means of visualizing relative similarities of the gamut shapes.
