Select Color Dialog

The Select Color dialog is described below with functions for how to access it. A list of the controls on the dialog box can be found in the table below.

Note: Value can go beyond 100% if picking colors from an HDR image and Saturation can go beyond 100% if picking colors from a Channel in a colorspace with a wider gamut than the color picking colorspace.

Note: Picking values for HDR images outside of the range as defined by the color picking OCIO colorspace, may result in clamped values.
