XY coordinates and color ref

Hi,

First of all i want to say i'm not a IT so i just try to do the best of me.

I’m working on a script to obtain a .csv document with the information about the colour RGB/CMYK and the XY coordinates for this colour to update in a BBDD.

I have a problem, i found a script that only shows one colour that I pick up with the eyedropper tool (Photoshop).

How can I pick different colours? how can I integrated the XY ref.?

Thanks in advance
