This coloring page features four mysterious figures wearing dark clothing, arranged in a line with space in between them. The background behind them is large and empty, creating an eerie atmosphere. To bring the scene to life, vibrant colors could be used to brighten up their clothing and make it pop. The background could be given some texture through the use of shadows and shaded tones. To further emphasize the mysteriousness of the scene, opt for darker, more muted colors. A gorgeous combination of both light and dark colors would be a great way to create an intimidating yet beautiful coloring page.
