When a designer harmonizes colors, the relationships between a set of colors are improved to increase the way they complement each other. The colors are harmonized to achieve a balanced, uniform and aesthetic effect for the viewer.  Scale and proportion are incremental in nature. Artworks don`t always rely on large differences in scale to create a strong visual impact. A good example of this is Michelangelo Pieta`s sculptural masterpiece from 1499 (below). Here Mary weighs her dead son, the two figures form a stable triangular composition. Michelangelo shapes Mary on a larger scale than the dead Christ to give more meaning to the central figure, both visually and psychologically. If they were both depicted in the same size, Mary would look awkward if she tried to weigh a full-size adult figure in her knees. First of all, we don`t realize how much bigger Mary is because Michelangelo is masterfully sculptor. The “principles of design” are mechanisms of arrangement and organization for the different elements of design in works of art.
Please note that different sources can easily list different versions of the Principles of Design, but the basics are much the same. The basic design principle of the accent is used either to highlight certain elements of a design (for example. B by using contrasting colors, enlarging an element, enlarging the white space around it, etc.) or not to emphasize (for example. B when a tiny “small print” is added at the bottom of a page). The visual arts manifest themselves through media, ideas, themes and creative imagination. But all this is based on fundamental structural principles that, like the elements we have studied, are combined to give a voice to artistic expression. Incorporating the principles into your artistic vocabulary not only allows you to objectively describe works of art that you may not understand, but also contributes to the search for their meaning. Elements or principles of visual design include contrast, balance, accent, movement, white space, proportion, hierarchy, repetition, rhythm, patterns, unity, and diversity. These design principles work together to create something that is aesthetically appealing and optimizes the user experience. Color harmony, often referred to as the “measure of aesthetics,”  examines which color combinations are harmonious and pleasing to the eye and which color combinations are not.  Color harmony is a major concern for designers, as colors always exist in the presence of other colors in form or space.
 The textile environment is well suited to integrate motifs into art. The pots and the firing of the threads create natural patterns that are manipulated by the position, color and size of the weaver. The Tlingit culture on the coast of British Columbia produces spectacular ceremonial covers that are distinguished by graphic patterns and rhythms in stylized animal shapes separated by a hierarchy of geometric shapes. The symmetry and high contrast of the design are breathtaking in its action. The symmetrical balance is the most visually stable and is characterized by an exact – or almost exact – composition design on one (or two) faces of the horizontal or vertical axis of the image plane. Symmetrical compositions are usually dominated by a central anchor element. There are many examples of symmetry in the natural world that reflect an aesthetic dimension. The lunar jellyfish fits this description; phantom light on a black background, but absolute symmetry in its design. In every work of art there is a thought process for the arrangement and use of design elements….
