The tool calculates the matrix for the conversion between RGB color spaces.
Enter the chromaticity coordinates for the source and destination color space or select from the predefined set. Clicking the Swap button will exchange source and destination.
If the source white differs from the destination white point, the selection of the chromatic adaptation transform (CAT) is relevant. The options are the CAT02 transform and the Bradford transform. Without a CAT, which is the the third choice, the RGB values will be re-balanced, i.e. the rows of the matrix will not sum up to 1.
