Most people have been using these basics for years, so there's nothing to be leery of. The basic elements are: color, line, shape, texture, and space.

Color represents emotion and allows objects to stand out from the background. When the primary colors--red, blue, and yellow--are arranged with the secondary colors between them, this is known as a color wheel . A designer's choice of color combinations can greatly influence the character of a display. Complimentary colors (opposite on the color wheel) create a sense of excitement and action, which is most useful in display work . When placed side by side, they intensify each other, but are seldom used in equal amounts. The most pleasing color schemes are those that combine families of colors--those that are near each other on the color wheel. Colors can advance and recede and have certain psychological connotations. For example, red suggests danger and passion (blood), blue suggests tranquility (sky), green suggests nature (leaves), and yellow suggests prosperity (sun). Remember these connotations are not ironclad, but can often be counted on to contribute additional emotional layers to a display.
Tips on using color in displays:
Lines represent order and give the eye explicit directions about where to look and how to interpret what it sees. They group related objects together and divide unrelated objects. The line is also the edge where two shapes meet--2 sheets of paper placed side by side have a "line" between them. Most often lines are functional rather than decorative.
Tips on using lines:

Shape is any type of form used in a display, remembering that the display case or bulletin board itself is a shape. The main problem is to arrange all of the different sizes and shaped items into larger and more important shapes, and then to relate them to the rest of the design.
Tips on using shapes:

Texture is the visual or tactile appearance of a surface. Surfaces can look or feel smooth, rough, soft, cool, or warm. They can look pleasant or unpleasant, which can have a dramatic effect on a display.
Tips on using texture:

Space is depth and dimension--objects that are in front of or behind things, around them, or projecting from them. Space adds interest, excitement, and contrast to your design.
