Abstract

The invention described in this specification is intended to assist in the maintenance of colour fidelity during the process of manipulating images while they exist in the digital domain and for when they are eventually transferred into the analog domain or are displayed on another digital red, green, blue (rgb) viewing system or device. The invention is a method for transforming a digital value representative of colour, that is displayed on an original rgb viewing system (P), such that when said transformed value is used by another rgb viewing system (Q) to display the colour the two displayed colours are matched. The method steps comprise the determination of the colour primaries in a predetermined tri-stimulus colour space for P. For a given digital value stimulus for P the viewable result of P as an expression of said colour primaries is determined. Then the colour primaries in the predetermined tri-stimulus colour space for Q; then determine the response of Q by combining the viewable result of P and the primaries of Q; and finally determine the stimulus for Q from the response by Q required to display the colour of the given digital value stimulus. The preferred tri-stimulus colour space is CIE XYZ.
