Colors in my library change CMYK value and hue yet keep the same HEX and RGB value...

[Ricco Comics]

Hi I've got this big issue that the colors I have saved in my library, such as the red in the 3 screenshots, keep same HEX and RVB value, but the CMJN value changes on each photoshop document I open.

Workspace is RVB 8 bits for the 3 of them.

I don't understand... And if i change the CMJN value then the HEX and RVB change... It's very problematic since I was refering to these colors for my line of drawing to keep some consitancy.

Did I miss something?

Thanks in advance for your help.

Best regards

Numbers are color space specific. They are undefined until associated with a specific icc profile.

Same numbers, different color:

@D Fosse  thank you very much!May I ask you how to associate my color with a specific profile?

[D Fosse · Accepted solution]

It's the profile embedded in the file.

If the file is untagged, doesn't have an embedded profile, the color is undefined.

Look at the status bar at the bottom of the image window. It can (and I would argue should) be set to show the embedded profile:

To define a specific color, use Lab. Lab is device independent and used as a reference color space. The numbers will then be calculated according to the document's color space.

@D Fosse thanks again for all your help, last question : how do I change the profile ? (by the way you are right they are different... See screenshots)
