This coloring page is quite a treat for any Harry Potter fan! The Gryffindor house coat of arms features a vibrant gold lion with a passionate red mane and a regal stare. Behind the shield is a silver sword with a gleaming golden handle that sparkles against the vibrant colors of the page. To bring this page to life, use bold and bright colors for the lion and the sword. Use a deep crimson red for the mane and deep gold for the lion. For the sword, opt for a calming silver with a warm golden hilt. Allow the colors to create a bold image that captures the essence of the Hogwarts School of Witchcraft and Wizardry and the brave Gryffindor house.
