What are the 2 categories of drawing material?
Drawing materials are broadly categorized into **dry media** and **fluid media**. Dry media includes pencils, charcoal, pastels, and crayons, which apply pigment directly to the surface. Fluid media, on the other hand, involves materials like inks, watercolors, acrylics, and oils, where pigment is suspended in a liquid binder and applied with brushes or other tools.
