RGB value looks different in two files

[M-Z-Jay]

I've got a coloured box that I need to change the colour of on multiple files. I have selected the box and changed it in all of the files, but it looks different in some of the files, and it eyedroppers with different values. All files use RGB workspace. I'm stumped. Can anyone help?

All the files may be using RGB (as opposed to CMYK or Grayscale) but what is the colour workspace as described by the documents' colour profile - e.g sRGB, Adobe RGB etc.  The number without the profile is meaningless and the same colour in different colour spaces will have different RGB numbers.

To describe a colour the RGB values and the colour space profile are needed.

Thanks for the super-speedy response Dave. However I made a mistake in my original post. Both colours eyedrppper the same value.

Both files use Adobe RGB workspace.

Not sure if this helps...

Both files use Adobe RGB workspace.

Just to make sure please set the Status Bar to indicate the Document Profile and post another screenshot.

What are the Eyerdropper Tool settings?

Are Adjustment Layers involved?

Some questions for clarity - as something appears off here.

1. Does the eyedropper show the exactly the same value in both those blue areas when switched to each document and clicked?

2. What is your eyedropper options set to, for example:

3. Although you say both are tagged Adobe RGB can you switch the bottom of your screen to show the profiles on both

4. Do you have any opacity/blending modes , adjustment layers in play

Edit - crossed post

Davescm you have hit the nail on the head. Although all of the files had come from the same agency they used different profiles. Once I changed the profile, and re-edited the colour box it was okay.

Thanks to both of you for your help. Much appreciated.

You're welcome - glad you got it sorted

Different color spaces. No, that's not "RGB", but sRGB, Adobe RGB or ProPhoto RGB.

Decide which one you want (if you don't know, the safe bet is sRGB) - and convert the others with Edit > Convert to profile.

Then the numbers will match.
