Using the Mouse and keyboard

I have created a drawing program using the mouse and keyboard. You can change the colour by:

• Pressing 'B' to add blue and 'V' to take away blue from the colour
• Pressing 'R' to add red and 'E' to take away red from the colour
• Pressing 'G' to add green and 'F' to take away green from the colour
• Pressing the space bar to reset the colour

You can also change the background by clicking the colour box at the top right and pressing any of the numbers on the numpad:

1. White
2. Black
3. Blue
4. Red
5. Orange
6. Yellow
7. Green
8. Purple
9. Pink
10. (0) Gray
