We present a method to calculate sets of RGB primaries that are white-point independent and have suitable gamut properties when evaluated with regards to surface colors. These primaries can be used as a basis for defining an output-referred color encoding intended for print applications. The resulting RGB sensors are sharp, i.e. decorrelated, emphasizing again that for imaging applications, the choice of a chromatic adaptation transform based on sharp sensors might be most appropriate.
