It is often shows that human eyes may see illusionistic images that can create dimension. Following are some of the examples that would illustrate the illusionistic images- The Bezold effect is an optical illusion, named after a German professor of meteorology, Wilhelm von Bezold (1837-1907), who discovered that a color may appear different depending on its relation to adjacent colors. The eyes play a variety of tricks on the brain that are common to most human experience. Some of them are useful to the artist/ designer or problems for the artist/ designer. Designer while creating 2-D design may take advantage of the illusionistic expression.

Note, that although the blue and gray rectangles are all of equal luminance, the ones seen in the context with the dark stripes appear brighter than the ones seen in the context with the bright stripes. Piet Mondrian in his theory of Pure Plastic Art demonstrated the quality of such dimensions (Plate19) without using the conventional light and shade. Thus, he produced the elasticity of colors by combining them against Pure Colors (Yellow, Blue, Red and Black and White). He demonstrated that the same color may create different dimensional effect against another color. Plate19. A & B Piet Mondrian Source:http://www.google.co.in/search?

Opaque color surface is more reflective (not to be confused with “shiny”). They cover and hide what’s under them. On the other hand transparent (or translucent) surface paint allows more light to pass through them. They appear to ‘see through’. Learning about and observing the opacity or transparency of paints enables artists to have greater command over techniques like glazing, layering, optical color mixing, or avoiding reappearance of earlier paint/ color, a bothersome effect where paint becomes more transparent as it dries, revealing what’s underneath. Many of Monet’s impressionist paintings shows the layer bellow the because of aging the upper surface color’s transparency. The 18th C Ad English Water color paintings had achieved the Plate20 A. Minimalist Design Plate 20. B Plate 20. C PaulCezanne The interior of the room design (plate 20A) uses the transparency technique to achieve the desires environment, “Ingenious design, this bathroom the minimalist spirit of transparency and plays of light. A large window separating it from the bedroom while linking it intimately. This allows him to enjoy the natural light that lands on the room lighting flattering. Intimacy is preserved or screened behind blinds suggests.” Ref. 20 A. http://tubreglazingx.com/a-bathroom-color ; May 26, 2012 Similarly the Plate 20 B illustrates the transparency technique to create sublime effect of colors in a 2D presentation. Paul Cezanne’s self portrait (20 C)shows the use of transparent color creating freshness and soft tonal color scheme.

We cannot perceive the edges of objects where object and background have the same luminance. If parts of a painting are equiluminant, their positions become ambiguous. They may seem to shift position or to float. The ‘blur’ edge creates an impression of dynamism instead of static condition. 2- D artist and designers have successfully applied such technique to generate dynamism. The combination of colors such as, blue and orange, violet and yellow, red and green, etc can create such impression of dynamism based on the size and area. Human eyes are sensitive to such combination of colors. Equiluminant colors have long been recognized by artists as being special because they can generate a sense of vibration, motion or sometimes an eerie quality. This strange quality arises because of a particular system can see something that the other system cannot; with only a particular system activation in isolation we can identify a particular object, but its position and motion (or lack of motion) are undetermined. Plate 21 Equiluminant (ambiguous) colors Plate 22 Impressionism (Claude Monet) The contrasting colors produce the invisible strength of line which slowly merges with another (background) while blurring the colors by mixing. Impressionist painters have created such color pallets where colors have merged with each other (Plate22). The above paintings typically express the Equiluminant Colors that are self contrasting because of the combination of primary and secondary (complementary) colors. Impressionist painters frequently applied equiluminant colors that created higher luminosity in the color scheme. Docsity.com
