Claim 16:
17. A method for color conversion in a multi-primary color system, comprising:
providing a color signal corresponding to XYZ coordinates of a color;
providing at least four primaries, at least four triads, and at least four XYZ-to-triad matrices, wherein each of the at least four triads includes three of the at least four primaries, wherein the at least four triads are selected such that a first triad includes a white point, a second triad includes the white point, and no other triads include the white point, wherein each of the at least four XYZ-to-triad matrices corresponds to one of the at least four triads;
multiplying the XYZ coordinates by the at least four XYZ-to-triad matrices to determine one or more of the at least four triads in which the XYZ coordinates are located;
setting all values in a resulting matrix from the multiplication of the XYZ coordinates and the at least four XYZ-to-triad matrices to zero if any value in the resulting matrix is negative;
determining a sum of primary components of the one or more of the at least four triads on a per-component basis;
dividing the sum by a number of the one or more of the at least four triads, thereby creating an updated color signal; and
displaying the updated color signal on at least one display device.
