I wanted to measure the average color values of a small area of a photo, so I ran the QCPA framework and converted that cone-catch image to RNL chromaticity. I then measured that photo to get the average X and Y color values. Is it correct to say that these values are how “red” or how “yellow” the area is (x and y, respectively), and the farther away from 0 the value is, the greater the color intensity? If not, is there a way to easily transform these data to reflect color intensity? Thank you so much.
