Color Inconsistency Issue

Hi,

I’ve encountered a strange color-related issue in Photoshop (video below) that’s driving me crazy. I’ve spent way too much time trying to fix it, but I can’t figure out what’s going wrong. I’d be really grateful if someone could explain what’s happening or suggest a solution.

Setup:

• Photoshop: Latest version
• OS: Windows 10 Pro (version 22H2)

The Issue:
When I copy and paste a hex color code into a shape layer, the layer doesn’t retain the exact color value I’ve entered. Instead, the color shifts slightly. While the difference isn’t very noticeable, it’s frustrating not knowing why this happens.

This issue occurs regardless of how or where I select the color (Hue Cube, Color Picker, Swatch, Shape Fill). However, I’ve noticed that the problem doesn’t occur when I’m working in RGB mode.

I’ve reproduced the problem in multiple ways, as shown in the attached video.

Any insights or fixes would be much appreciated!

Thanks in advance!
