This is especially important when, perhaps, I'm using a georeferenced map, for example, that is already ADA compliant (colors) and I need to get my symbology as close as possible. Can I do this in Adobe? Yes, but how many folks have Adobe PS?
Best I've been able to do is use an outside program (like MS Paint) to get a screen capture, use THAT eye dropper, get the details out of the Colour Customization and then type those numbers into the RGB in Pro - then switch to CMYK and adjust as needed - i.e. making water labels in the same family, but just darker, then add black. It would save loads of time and frustration if the eye dropper tool could be added in Pro. Thank you!
For now I just double click the Layer in the Map Frame --> and in the Symbology tab click the color drop down --> Color Properties --> write down the RGB values. But, I'm all for having the Eye Dropper in Pro!!
For use with picking any colour (basemap or otherwise) try using ColorPix (ColorPix - Download). Same function as eye dropper tool and can store your colours for reference.
I used this daily in ArcMap to color match layout text with client logos. The logo is on the layout as an image and the color dropper is used to match.
I also use this to produce annotation halos that match the background color(s). This is not helped by viewing the RGB values of color swatches because they do not include the colors used in basemaps.
I use it in desktop all the time when I am trying to match the background color with the background of a copy/pasted excel sheet that I have in the layout view.
