Castle on a hill at midnight coloring page

A castle with pointed towers and little flags stands on a hill, bats crossing the sky, two ghosts drifting past the walls and a full moon behind. The stonework is drawn block by block and each block does not need its own color: two greys, laid down in an irregular pattern, do more than twenty. The windows lit from inside are the place for yellow. The haunted mansion in the first Halloween batch is the same idea with a roof instead of towers.

How to color Castle on a hill at midnight

1. Two greys on the stonework, alternating blocks irregularly.
2. Yellow in the lit windows, red or purple on the flags.
3. A night blue sky with the moon white, and the ghosts left white too.
