Set Background color
Use this block to change the background color of your project. The default background color of any project is white. You can pick one of the colors in Hopscotch, or enter an HSB or RGB value to use a custom color.
The background layer is underneath the drawing layer. So when you change the background color, any trails made with the Draw a Trail block will remain. When you clear drawings, it will clear all trails and leave the background color.
