Recolor multiple layers panel layers at the same time
In Photoshop, you can select multiple layers, and add a color marker at the same time to all of them. I often use the colors of layers in Illustrator for UI and packaging design to separate visually which layers are finished (green), and which ones I still need to work on (red). But I have to double click each layer one by one in order to change the color.
Yep, there is a way to change the color of edges for a selection of layers — 'Options for Selection' command in the Layers panel’s flyout menu.
But perhaps the original poster meant colored backgrounds to mark layers? Like Photoshop allows to and like we can do with actions in button mode?
If yes — please make a separate request about this.

There is a way to do this. Select the layers you want to change and from the fly-out menu in the Layers Panel, choose "Options for Selection"
highlight the desired layers, select the hamburger menu on the layers panel, select options for selection
