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.
highlight the desired layers, select the hamburger menu on the layers panel, select options for selection
