If you’re the owner of a mural, you can choose the color of your canvas. Maybe you want something with a little more contrast, or a darker background you find easier on the eyes for longer collaborative sessions. Whatever the reason, the choice is yours.
To change the canvas color:
Click the arrow next to your mural’s name.
Select Mural settings.
Click a Canvas color to select it. Faint white is the default.
Click Save changes.
And there you have it! A brand new canvas color to work on. You can change the color to something new or back to the default at any time by repeating these steps.
