Color transformation in 3D color space

A computer readable medium including computer instructions for transforming color information into a standard color space, the computer instructions comprising instructions for:

• storing a plurality of RGB color points representing each vertex of at least one three dimensional cube, wherein each of the RGB color points represents a difference between a capacity of an output device and a selected color standard;
• dividing the three dimensional cube into a plurality of tetrahedrons;
• determining which of the plurality of tetrahedrons corresponds to an input RGB pixel with an R, G and B component;
• calculating a 3×3 matrix based on each vertex of a tetrahedron corresponding to the input RGB pixel;
• and
• multiplying the 3×3 matrix by the components of the input RGB pixel, wherein an output RGB pixel conforming to the selected color standard is calculated.
