Abstract
Described are examples for determining an effective color space of a display. A two-dimensional parametric surface that intersects a color volume defined for the display can be defined for at least one color volume vertex. A flat bitmap to which the two-dimensional parametric surface is mapped can be displayed, on the display, for the at least one color volume vertex. A selection of a point on the flat bitmap that corresponds to a perceived maximum color can be received for the at least one color volume vertex. The effective color space of the display can be determined based at least in part on the perceived maximum color selected for the at least one color volume vertex.
