let's say i will pick a color at the tooth neck with some tolerance ex:51x51 and paste values (RGB or L,a,b) into excel. i could put there rgb or Lab values for all tooth shades. how to check which color is closest? should i compare sum of R+G+B? i'd like to tell how many % should i take of color A1 and how many % of color A2 for example to have this picked color.
