This sampling scheme has been used successfully in different research works from computational color science to color image processing. The main objective of this paper is to demonstrate that the number of color samples computed is dependent of the color gamut boundary considered and that the number of discernible color can be set to the JND. The second objective of this paper is to demonstrate the relevance and the accuracy of the hexagonal grid sampling method applied to the CIELAB color space
