With colors, textures, and photos, you can add details that make a 3D model look realistic and complete: Colors are like paint. Textures add realistic materials, such as carpet, tile, grass, wood, glass, and anything else you can capture as a digital image. Photos can be pinned to your model (or just a face within it). In SketchUp’s Materials panel (Microsoft Windows) or Colors panel (macOS), you find predefined colors and textures, which you can edit. Or try mixing your own colors or creating a texture from a photo.
