    how to calculate delta e for two areas ?

    Hi all, is it possible to calculate delta e for an area in photoshop? I do not want to use the sampler to get the values, I am using the histogram to get the area LAB or RGB values. Thank you in advance Taz

    delta E

    i have a color sample in L,a,b mode used as 3d coordinates. I also know the coordinates of a few other colors (A1,A2,A3,etc) of which A1 and A2 are the closest. A2 in this case is the closest one. how should i measure how many percent of A2 color should I mix with A1 color to get the best match...
