Do not put multiple elements in the same layer! 7. Now we can begin by adding a background colour to the canvas in this new layer. In the Tool Palette along the left side, click on the Flood Fill Tool (paint bucket icon). 8. Make sure the Color panel is open on the right side. That panel is used to select a colour that you want to use to fill the background layer. Click on the white circle, which represents your Fill colour to be used when you draw anything on the canvas. With that circle selected, click in the green area below and notice the circle is now green rather than white. 9. Click now on the canvas to fill the background with green. 10.

As you will see when you drop the Green background layer on top, the canvas becomes green again rather than red because Green Background is the upper layer now. Drag the Green Background layer down to the bottom to see the Red layer show up again.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
