Eighteen color specification systems are compared, each composed of different combinations of color space (red-green-blue, RGB; opponent channel, OPP; hue-saturation-value, HSV), slider type (plain, static, dynamic), and background context (achromatic, chromatic). A total of 83 undergraduate students, both male and female, participated in the study.

Color matching performance was analyzed to yield measures of time, physical effort, accuracy, and convergence speed.

The results indicate that the OPP color space led to greatest convergence and most user comfort, while the RGB space ranked second in terms of convergence, and the HSV space ranked second in terms of user comfort. Among the slider types, the dynamic sliders were superior according to almost every usability measure, followed by the static sliders and then the plain sliders. Context had a mixed effect in that the achromatic background led to slower but more accurate matches than did the chromatic background.Texas A&M UniversityTassinary, Louis G.2010-05-28T18:01:03Z2010-05-28T18:01:03Z1994-121994-12BookThesisElectronic Thesistextelectronicborn digitalhttp://hdl.handle.net/1969.1/90683en_US
