The 3-D viewer below may be used to display one or two working space gamuts in any of four different color spaces. The secondary gamut is drawn in fainter colors than the primary gamut so the two are easier for the eye to separate. All gamuts are shown adapted to the D50 reference illuminant using the Bradford transform.

Please select either the single gamut you wish to view, or the two gamuts you wish to compare, using the primary and secondary gamut selectors below. Then click the grey box to update the display. There may be a delay of a few seconds before the display appears.

This viewer does not work with Safari 3 on Windows XP, but works with Safari 5 and all other browsers and platforms with which it has been tested, including Firefox and IE with Windows 8 or Windows 10. Java errors and exceptions are often caused by blocks imposed by anti-virus software. In the case of Zone Alarm, it may be necessary to disable Web Scanning.) If your browser blocks Java, it may also be necessary to list this website (http://www.openphotographicsociety.org) in the Exception Site List under the Security tab in your Java control panel.
