Consists of three colors found on the color wheel that are equally spaced apart from each other.

The ratio of the transmitted radiant flux to the incident radiant flux under specified geometric and spectral conditions.

These are man-made illuminants that harnesses its energy and light source from electricity, gas, or heat (luminescent, gas discharge, and incandescent).

Is a system of rules and guidance for mixing various colors.

Ratio of the radiant flux reflected from the specimen to the radiant flux reflected from the perfect reflecting diffuser under the same geometric and spectral conditions of measurement.

The human eye can only detect visible light spectrum or wavelengths from 380 to 700.

Sawtooth, zig-zag, patterns, motifs of sharp corners and peaks of lines.

The ratio of the absorbed radiant flux to the incident radiant flux.

High frequency

Vertical, horizontal or diagonal lines has their own character or visual representation.

Noticeable level of difference between two colors.

The concept in color theory that uses geometric relationships to identify harmonious color combinations.

Radiant flux falling on or striking a material.

Bending of light as it passes from one transparent substance into another.

Having an appearance that is independent of illuminating and viewing geometry.

Composed of many different colors and the various mixtures of light compose the colors that we see.

Amount of light reflected in a surface.

Reflection that excludes diffuse reflection, as in a mirror.

Colors made by mixing primary colors.

The process whereby radiant energy passes through a material or object.

Indicates a position in space.

Refers to the dominant color family.

Emission of light ascribable to nonthermal excitation.

Photoluminescence that continues after excitation ceases.

Having an appearance that is dependent on illuminating and viewing geometry.

The study of how colors affect perceptions and behaviors.

Color spectrum bent into a circle.

A combination of four colors equally spaced around the color wheel.

Refers to a color scheme that is comprised of variations of one color.

Another word for color.

Low frequency

The use of three evenly spaced colors on the color wheel with the EQUAL DISTANCE between all colors.

A point extended becomes a ____. Conceptually, a ____ has length, but no width or depth.

Lines directed towards a vanishing point.

Luminescence produced by the absorption of light (excitation); distinguished from ordinary reflection by a time delay and, usually, a shift toward longer wavelengths.

From point to line, and lines to planes. An enclosed segments/components of lines forms planes and shapes.

Color schemes are made up of a color and it’s complements closest analogous colors.

Deals with the lightness and darkness of color.

Energy that is transferred by electromagnetic radiation. The Radiation spectrum, which includes gamma rays, x-rays, radio frequencies, microwaves, light and heat.

Reflection that excludes specular (mirror) reflection.

Colors that mix primary and secondary colors.

The transformation of radiant energy to a different form of energy by interaction with matter.

Refers to the intensity of color. The amount of white light mixed with a hue.

Colors that can not be created by mixing other colors.

Light that occurs naturally without the involvement of humans.

Colors opposite from one another on the wheel.

Photoluminescence that ceases when excitation ceases.

The process by which radiant energy is returned from a material or object.

Lines with a particular width of thick or thin.

Ratio of the reflected radiant flux to the incident radiant flux in the given conditions.

It is an electromagnetic range that is radiation (Non-visible/Visible Energy, Frequencies.

Power emitted, transmitted, or received in the form of radiation.
