As you can see, since the gold crayons are the most important, these will be the main focus of this post. To color one gold square, you need 2 gold crayons on the 1st page, 4 on the 2nd page, and 6 on the 3rd page. Also in the dungeons, where you farm your leveling materials, gold crayons are the rarest ones you will get.
