This Harry Potter - Coat of Arms of the Ravenclaw faculty coloring page is truly a work of art. The blue background creates a majestic look and the silver-colored raven in the center gives it a timeless feel. The silver necklace around the raven's neck and the key that it clutches in its beak have a regal appearance. Additionally, the silver stars scattered throughout the background give it a magical feel. To highlight the detail of this page, I would use a variety of blues and silvers for coloring. The Raven should have a light blue hue for its body and a slightly darker blue for its wings. Additionally, the necklace and key should be a metallic silver color to give them a realistic shine. Lastly, a lightly shaded silver can be used for the stars to give them a twinkling appearance. This coloring page is sure to amaze any Harry Potter fan and will make a beautiful piece of art.
