Choose a color from the palette, or tap the + button to create your own custom color.
Make sure FILL is on, then tap or click the area you want to color.
Your progress saves automatically on this device, so you can refresh or come back later and keep going.
Use UNDO to go back one step. Use FIT to recenter the artwork. Use RESET only when you want to start over.
