This coloring page features a mysterious witch with some arcane ingredients in her cauldron. She is dressed in a classic witch robe and stands with a long, wooden spoon in-hand, fully in control of her craft. Behind her, a storm is brewing, casting its dark hues across the page via the lightening flashes outside the window. This witch appears to be incredibly powerful and mysterious, with each of the many bottles and jars around her likely carrying powerful spells and enchantments. To bring this scene to life, I would use deep hues of midnight blue to shadow the stormy sky, bright oranges and yellow for the lightning outside the window, and dark purples and greens for the witch's attire and the mysterious symbols on the bottles.
