There’s neat trick to limit influence of the adjustment layers in Photoshop. Just press alt (Or option key on mac) while clicking between layers. In this way we can attach adjustment layer to the layer below. A little arrow will appear. Clicking the arrow with alt (/option key on mac) will remove the connection.

This can be used for solid colours as well, and limit their influence on a simple layer below. In this way we can establish a truly non-destructive workflow. Check out the video below for this trick.
