What tools are typically available in coloring apps?

Coloring apps usually offer a range of digital tools to enhance the coloring experience. Common tools include various brush types (e.g., pen, marker, crayon, watercolor), an eyedropper for color selection, a fill bucket for quickly coloring large areas, and an eraser. Many apps also provide blending tools, layering capabilities, and symmetry tools for mandalas. More advanced features might include custom brush creation, texture brushes, and gradient tools. Most apps offer undo/redo functions and the ability to zoom in for detailed work. Some also include special effects tools like glitter or metallic colors to add extra flair to colored images.
