What defines form?

What defines form?

• A. Color
• B. Texture
• C. Light and Shadow
• D. Size

Answer: (C)

Light and shadow define form by showing the volume and depth of an object on a flat surface. The way light wraps across surfaces creates highlights, midtones, and shadows that reveal curves, edges, and planes, making a shape read as three-dimensional. Color indicates hue, texture describes surface feel, and size relates to scale, but none of these alone establish the solid, volumetric presence that light and shadow deliver. By adjusting how light falls and where shadows fall, you communicate the form—the roundedness, flat planes, and overall mass of the object.
