The document discusses six key components of visual design - line, color, form and shape, space, texture, and value. It provides examples of different types of lines and how they can be used to convey different meanings or feelings. Color is described as having an immediate impact and how different colors can elicit different human responses. Form and shape refer to the 3D and 2D contours of an object. Space in a design can be open or cramped. Texture describes the surface feel of an object. Value refers to the lightness or darkness of a color. Seven principles of design are also outlined - balance, rhythm, emphasis, proportion/scale, movement, contrast, and unity.
