Photoshop: Duplicating layers doesn't retain the layer's color in the layers panel

Hi Glenn, I'm not able to reproduce this issue. What version of Photoshop are you using? What OS/version are you running on?

2015.0.1 in Win7. It happens if I just create a document, right click Layer 1, select "red", then hit ^J. Layer 2 is back to grey in the layer panel instead of staying red.

Got it. Oddly it doesn't happen with 2 or more layers. Only the single layer case.
