摘要：A method, system and computer readable medium for transforming three
dimensional (3D) color information into a color standard is described. A 3D cube defined by eight RGB color points representing the eight vertices of the 3D cube is stored. Each of the eight points represents one of the colors: red, yellow, white, magenta, blue, black,
green and cyan. In addition, each of the eight points represents the difference between the capacity of a display and the color standard. The 3D cube is divided into six tetrahedrons and the tetrahedron corresponding to an input RGB pixel is selected. A 3×3 matrix based on the vertices of the selected tetrahedron is calculated. The 3×3 matrix is then multiplied by the components of the input RGB pixel to produce an output RGB pixel conforming to the color standard.
