Same color, looks different in my 2 documents

[umagurl77]

Hello,

I have a file that was supplied to me. I am remaking it from scratch. The RGB colour that was supplied to me, when I use the same colour in a new document, it looks different. I'm sure it's a colour settings thing, but I'm not sure where to look.

Any advice?
Thx!

What are the two images’ Color Spaces?

I recommend you set the Status Bar to indicate that.

Thanks. They are both different. I guess that is the problem? How do I fix that?

Yes, the same RGB-values can appear differently in different Colour Spaces.

You can either assign the same profile to the offending image or you can convert (a copy of) the original image to the Color Space you want to use and read the new values.

They not only can, but they will. Even neutral grays will shift a little between sRGB and Adobe RGB, since the tone response curves are different.

I would not want to rule out that there could be some RGB-values that appear identically in more than one RGB-space but I am not about to make extensive tests …

No, let's not go there

If an RGB- or CMYK-image is untagged then it will be displayed as if using the respective Working Space (see Edit > Color Settings).

If an image has an embedded ICC Profile it will be displayed on the basis of this.

I'm not sure how to convert my offending image to match the  profile I want...

If you create the new document from scratch you can simply start with an image you assign the correct profile to (in the New Document-dialog or via Edit > Assign Profile).

Great. Thanks. Done!

Thx for posting! I had a set of files I use to make 3 different shaped files for various social media posts. With some lighter colors, 1 file would look weird, like really bright green vs a more pastel green in the other 2 files. 

I made a new file with the correct color profile and dragged all my layers over from the old file. The colors stayed weird, so I reapplied the correc color, it updated and looked correct. 

From here on out, those files will all look the same on updates. THANKS!!
