Accepted conventions related to the organization of visual art elements in more complex units. Included: Color is the result of light that is reflected from an object to our eyes.  The color that our eyes perceive is determined by the pigment of the object itself.  Color theory and color wheel are often mentioned when studying color combinations in visual design.  Colour is often seen as an important element of design, as it is a universal language that represents the countless possibilities of visual communication.  Unity refers to a kind of connection between all the visual elements of a work of art. Like harmony, it is a bit of a vague term that is difficult to use to objectively analyze art. The chart below shows a strong sense of unity using similar shades used throughout the table. Although there is a strong contrast between light and dark areas, there is a sense of unity using similar hues (dark yellow, orange and green are used in the foreground and bright yellows, oranges and greens in the background). A good design contains elements that guide the reader in the order of meaning of each item. The type and images should be expressed from the most important to the least important. Dominance is generated by contrast size, positioning, color, style or shape.
The center of gravity should dominate the design with scale and contrast, without sacrificing the unity of the whole.  Design elements are the basic units of each visual design that form their structure and convey visual messages.   The painter and design theorist Maitland E. Graves (1902-1978) who tried to explain the basic principles of aesthetic order in visual design defined in his book The Art of Color and Design (1941) the elements of design as line, direction, shape, size, texture, value and color, and concluded that “these elements are the materials from which all designs come from.”  The line is the basis of any drawing. It is the first and most versatile visual elements of art. Line in a work of art can be used in many different ways. It can be used to propose form, pattern, shape, structure, growth, depth, distance, rhythm, movement and a set of emotions. A shape is defined as a two-dimensional area that detaches from the space next to or around it because of a defined or implied boundary or because of differences in value, color or texture.  Shapes are recognizable objects and shapes and are generally composed of other design elements.  Texture refers to the physical and visual qualities of a surface. [Citation required] Diversity refers to the use of different qualities or instances of visual elements.
Diversity can be used to break monotonous or repetitive areas. The visual texture, also called “implicit texture,” is not recognizable by our sense of touch, but by our visual sense. [Citation required] Visual texture is the illusion of a real texture on a two-dimensional surface.  Any texture that is perceived in an image or photo is a visual texture.
