Layer Colours

Would it be possible to assign a colour to an added item layer?

I know we can rename layers but a visual aid would be great. It Photoshop you can assign a colour to a layer or folder in the layers window to make it quicker to identify layers.

For instance, I could assign my Time layer the colour Red, my Date layer Blue and a weather conponcom Green (or any colour I choose).

Thanks in advance.
