A method based on the chromaticity discrimination ellipses is proposed for calculating the color difference between two colors. This method calculates the color difference by counting the number of just noticeable differences between the two colors. The color difference formula CIEDE2000 and the proposed method are compared. It is shown that CIEDE2000 is not suitable for predicting the threshold color difference.
