I asked 2 photoshop experts I know but they haven't got a clue because all my settings are exactly the same, in both files. (except the RGB type !! I'm not sure. Please read on) I use RGB color, 72DPI, 8 bits / channel. No adjustments (filters, like greyscale, etc ...) are selected / used. The layers are both normal, and opacity and fill are 100% (yes, in both files).

I took two screenshots, and you can see the difference:

Both colors are ff795d, but that doesn't matter, any color I use gives me the same problem: they both look different. Now, I know the CMYK settings (see screenshots) are different, but when the settings are the same the color changes. Why is this happening and how do I solve this problem?

My guess is I'm working with different a type of RGB. It's sRGB IE61966 - 2.1 in the file I created (file info > raw data) but I can't find that in the file that started with a screenshot.

If that's the problem, how do I change / convert the RGB, once the file is already open?

Thank you.
