Duotone and Pantone Colours

[goodnightladies]

I have different sets of images that I turned into duotones with different pantone colours. Ie red, yellow, green, blue. I left out an image from each set and I need to go back and make that remaining image the same pantone colour. Is there anyway I can find out the pantone colours I used so the remaining images are the same colours for their respective sets?

Thanks

If i understand problem right, then on that image where is pantone which you want to know and go Image/Mode/Duatone. There is Pantone name.

Sorry I forgot to clarify. For the purpose of the project I'm working on, I converted the images back into RGB (to save as JPEG) after I turned them into duotones.

Only thing you can do is try find darkest point on that rgb image. Then on Color panel (or on tool bar) click on that colorbox. That will bring up Color Picker dialog. Click Color Libaries. And hope that it's correct one.
Actually if you find on rgb image absolutle "black" point where in duatone was 100% color fill then you'll have your pantone correct, if not then pantone will be too light and you'll have find it manualy.

Welcomen!

But i'll repeat the precision of pantone will depend on that finding absolutle "black" point.
