Is there a way to get the CIELAB colour when using the face colour mask?

New Here ,

Hi all,

I got images of faces that I would like to to a colour mask on (using the mask function in lightroom), then manipulate the colour using the CIELAB colour space? Is this possible at all? This is for a research project so the values need to be very precise. I also need to apply multiple masks (160 in one experiment) to the same photo (participants will see one mask at a time), and the experiment will include 50 different images each with multiple masks, is there a way to automate this (e.g., link lightroom to MATLAB or something similar)?

Kind Regards,

Anna
