Hi
Our company logo uses 3 colours, 100% cyan, 100% magenta and 100% yellow.

We have rgb values for all these from historically when we have converted the logo in illustrator.

 

However, I have converted fromm CMYK to RGB today and the values are different to those historic values.

 

Why would this be? I now am confused what the rgb values should be.

 

Any help would be greatly appreciated.

Color management is obviously set up differently now. Or different color profile.

Did you perhaps update to 25.2.1 recently?

And you also don't have the latest Photoshop version? Then it would at least not be caused by the bug.

So what you need to do is check the color management settings and the color profile you are using and compare this to the previously used settings.

Hi

 

Yes the colour profiles are the same. The colours visibly match but the rgb values are a couple of numbers different. So visibly I dont have a discrepancy but seeking to understand why this is.

 

thanks

And "historic" means?

 

Couple years ago you maybe haven't use color management for conversion.

Maybe you adjusted the numbers and didn't rely on color management alone.
