Term Definition
Color Theory
Color The effect produced on the eye by light waves of different wavelengths.
Hue The names of the colors:  Red, orange, blue, etc.
Additive Colors Colors created by natural light (red, blue, green) when equal amounts of red, blue and green light are mixed together they create white light.
RGB RGB is an acronym for Red, Green, Blue - monitor or light colors
Subtractive Colors Colors produced by mixing pigments; paint, crayons, ink, etc.

CYMK is an acronym for Cyan-Magenta-Yellow-Black. CMYK is a color model in which all colors are described as a mixture of these four process color. CYMK is a subtractive color paradigm that is computer printer based.

Shade The dark values of a color or hue.
Tint The light values of a color or hue.
Saturation Saturation is a measure of a color's pureness and brilliance.

When you use any graphic software program, colors are interpreted in one of three modes, RGB (Red, Green, and Blue), CMYK (Cyan, Magenta, Yellow, and Black), or HSV (Hue, Saturation, and Value).

Analogous colors

Are a palette of compatible color combinations that blend well together. They are neighbors on the color wheel.

Complementary colors

Are colors that are opposite each other on the color wheel. They contrast, enhance and intensify each other.

Monochromatic colors

Are all the hues (tints and shades) of a single color.

Triadic colors

Are high-energy colors that are found by choosing three colors that are separated by 120 degrees on the color wheel.

Elements of Art
Color That which is perceived when light hits and reflects off an object. Three properties of color are Hue (name of a color), Intensity (strength of a color) and Value (lightness or darkness of a color)
Line A continuous mark made on a surface
Form Adds perspective, gives depth to a two dimensional objects and encloses or takes up space.
Space The illusion of space is created through light and shadow and includes the use of white space.
Shape Two-dimensional objects (circle, square, rectangle, triangle) that enclose space.
Texture The surface quality or feel of an object:  Smooth, bumpy, etc.
Principals of Design
Balance Symmetry and asymmetry
Emphasis Used to make something stand out, like dark next to light
Proportion The size of objects; large next to small.
Movement the visual flow that creates a sense of motion and guides the viewers eyes and includes rhythm and repetitive elements.
Variety The use of different or contrasting elements to add interest
Unity How all the aspects of a work of art work together
Font and Typefaces
Serif Serifs are the strokes attached to the ends of character's body
Sans Serif Sans Serif refers to typefaces that do NOT have strokes attached to body of a character.
Script Typefaces that appear to have been handlettered.
Decorative Fun, distinctive, eye-catching fonts that attract attention and help convey a meaning. Can be hard to read and should be used selectively. Limited uses.
Typography The style or appearance of text; the art or procedure of arranging type.
Kerning Space between specific characters that varies over the course of the word.
Tracking Overall space between characters (character spacing).
Leading The space between lines of text (line spacing).
Hierachy Used to guide the reader's eye to what is important.
File Formatting
Pixel The smallest component of an image or picture on a monitor (usually a colored dot); the greater the number of pixels per inch the greater the resolution.
Lossy Some data is lost during compression. This process is irreversible.
Lossless No data (in a technical sense) is lost. Therefore, the compression process is reversible.
Vector Graphics made of points, lines, curves, and shapes, which are all based upon mathematical equations to represent an image. Resolution independent.
Raster Images made up of pixels laid out in a grid. Dependent on resolution
Interlaced With interlaced GIF files the image data is stored in a format that allows browsers that support interlaced GIFs to begin to build a low-resolution version of the full-sized GIF picture on the screen while the file is downloading.
Non-Interlaced The conventional (non-interlaced) GIF graphic downloads one line of pixels at a time from top to bottom, and browsers display each line of the image as it gradually builds on the screen.
PPI Pixels per inch is a measure of image resolution
DPI Dots per inch is a measure of printing resolution
