shape and value
1 answer
Shape refers to the outline or contour of an object, while value refers to the darkness or lightness of a color or tone. In visual art, shape and value are fundamental elements that help to create form and depict space. Shape can be abstract or representational and can be two-dimensional (such as a flat shape on a canvas) or three-dimensional (such as a sculpture). Value, on the other hand, is created by the contrast between light and dark areas and helps to create depth and volume in an artwork.
