Different color text with the same color code

[Daniel34590766eykg]

The CD and the "Anti-Gatekeeping" text have the same color code, but the text is still a different shade of green. I think it might have something to do with the text's appearance being a group? I don't know how to fix this. Can anyone help?

Photoshop thinks they're the same. How are you determining that they are different?

Is the CD a vevtor object? Or a placed image?

But apart from that: this might be caused by visual perception and the dark frame around the text as Doug already pointed out.
