It’s nice that you can change your workspace colors via Photoshop (PC: Edit)>Preferences>Interface; but did you know that you can also change the color around your canvas in the document window to anything
you want. This is the workspace area outside the canvas when you’re zoomed out and you expand the document window. Right-click in this area and you’ll see a list of colors, including Select Custom Color at the very bottom. Choose Select Custom Color and the Color Picker will appear. Choose any color you like, and click OK. Just be aware that changing the color around your canvas can affect how you perceive the colors in your image, so that iridescent pink may not be the best choice after all!
