1. Set the color and size using the color picker. The current color is at the bottom right of the screen (don't worry, this won't show up in the playback). 2. Press space to pause and unpause. 3. Use the mouse to draw. 4. To clear the drawing, press R and confirm. 5. To show your drawing to others, press F and confirm that you are done, then remix the project. 6. Watch the playback in turbo mode for an actual speed draw.
Also take a look at what others have made! https://scratch.mit.edu/projects/105754189/ Need the RGB value for any color? http://www.rapidtables.com/web/color/RGB_Color.htm All coding is by me. You can always remix and show others your drawing! Love it, and be sure to follow!
