There are five elements in art:
Color has three qualities. Hue, Value and Intensity:
Colors can be related to each other in the form of a wheel.
The PRIMARY colors are:
red, yellow, blue
The SECONDARY colors are produced by mixing two primary colors and are:
orange, green, violet
The INTERMEDIATE colors are produced by mixing two adjacent (secondary + primary) colors
The NEUTRAL colors are:
black, white, gray
Complementary colors are opposite each other on the color wheel. Violet is the complementary color of yellow, green is the complementary color of red, and blue is the complementary color of orange.
When mixing paint, addition of the complementary colors will dull the color.
Complementary colors placed adjacent to each other will intensify the colors.
Warm and Cool Colors
Red-violet, red, red-orange, orange, yellow-orange, yellow, and yellow-green are warm colors. They seem to come toward us or advance. Blue-violet, blue, and blue-green are cool colors. They seem to recede away from us. Green and violet are usually considered between warm and cool. Depending on the particular value and intensity, they can be either warm or cool.
Lines can establish movement, direction, and contour.
Horizontal Lines gives a quiet, restful feeling
Vertical lines gives a feeling of strength
Diagonal lines usually denotes action
Shape is an area defined by color, contrast, line, and/or texture. Shapes can be geometric, amorphous (free-form), etc.
A shape can have personality as influenced by the lines that create it or the overall shape itself. For example, shapes with vertical and horizontal edges appear rigid and tense. Shapes with fuzzy, indistinct edges appear soft or relaxed. Shapes with soft curves appear to flow or imply movement, and shapes that overlap with other shapes create energy, tension, or rhythm, depending on how they overlap.
The feeling of space in a drawing or painting is always an illusion. Artists combine the use of light and dark value with other techniques to create space. How an artist uses space or chooses NOT to use space adds a great deal to a work of art.
Space can be two-dimensional or three dimensional. A space can be positive or negative.
Three-dimensional artworks create their own space
Texture refers to the surface quality look or "feel" of an object - smooth, rough, slick, soft, etc. Textures may be actual (felt with touch - tactile) or implied (suggested by the way an artist has created the work of art -visual).
