Fundamental Elements of Visual Composition and Color Theory

The Point

The point is a visual element that has neither form nor dimension. Functions: As an expressive element, it achieves volume effects, chiaroscuro, and diverse textures. Compositional elements: It creates visual tensions that suggest direction and movement.

The Line

The line is the trajectory of a moving point. Functions:

• Expressive: Can be uniform, objective, or modulated/subjective.
• Composite: Vertical, horizontal, inclined, curved, or straight.

The Shape

The shape arises when a line closes on itself. It is defined visually by its shape, size, color, direction, and texture. Features:

• Three-dimensional feelings: Achieved through differences in size, color, texture, overlap, curvature, or shading.
• Volume settings: Used in sculpture and architecture.

Texture

Texture is a plastic element defined as the appearance of a surface. Classification:

• Smooth, rough, or granulated.
• Uniform or irregular.
• Natural or artificial.
• Tactile or visual.

Color and Light

The Color: A set of sensations that occur in relation to nerve stimuli in the brain. The Light: An electromagnetic wave transmitting energy. White light is the set of all independent lengths of the visible spectrum. Additive light is the sum or mixture of all colored lights that produce white light.

Light and Pigment Colors

• Primary Light Colors: Yellow, cyan, and magenta.
• Secondary Light Colors: Red, green, and blue-violet.
• Complementary Colors: Mixing a primary pigment color and a secondary color that does not contain the primary.

Color Coding and Qualities

Qualities:

• Tone: Identifying the color.
• Value: Degree of lightness or darkness.
• Saturation: Degree of purity.

Chromatic Systems

Colors are coded and sorted according to their position in the spectrum. Tertiary Colors: Formed by mixing a primary and an adjacent secondary color on the wheel.

Chromatic Harmony

The relationship established in a composition between two or more colors:

• Related Colors Harmony: Mixture of tones that are close in the chromatic circle.
• Complementary Colors Harmony: Mixtures of colors opposite each other in the chromatic circle.

Note: A pigment is a particular field belonging to a visible frequency spectrum. The purest pigments are those that are not altered.
