Creativity

Creativity is a mental and social process involving the generation of new ideas or concepts, or new associations of the creative mind between existing ideas or concepts. An alternative conception of creativeness is that it is simply the act of making something new.

Design

As a verb, "to design" refers to the process of originating and developing a plan for a product, structure, system, or component with intention.

As a noun, "a design" is used for either the final (solution) plan (e.g. proposal, drawing, model, description) or the result of implementing that plan in the form of the final product of a design process^.

Graphic

Graphics are visual presentations on some surface, such as a wall, canvas, computer screen, paper, or stone to brand, inform, illustrate, or entertain. Examples are photographs, drawings, Line Art, graphs, diagrams, typography, numbers, symbols, geometric designs, maps, engineering drawings, or other images.

Vector Graphics

Vector graphics is the use of geometrical primitives such as points, lines, curves, and shapes or polygon(s), which are all based upon mathematical equations, to represent images in computer graphics.

Raster Graphics

A raster graphics image or bitmap is a data structure representing a generally rectangular grid of pixels, or points of color, viewable via a monitor, paper, or other display medium. Raster images are stored in image files with varying formats

Layout

Page layout is the part of graphic design that deals in the arrangement and style treatment of elements (content) on a page.

Graphs

A graph or chart is a type of information graphic that represents tabular, numeric data. Charts are often used to make it easier to understand large quantities of data and the relationships between different parts of the data.

Diagram

A diagram is a simplified and structured visual representation of concepts, ideas, constructions, relations, statistical data, etc, used to visualize and clarify the topic.

Symbols

A symbol, in its basic sense, is a conventional representation of a concept or quantity; i.e., an idea, object, concept, quality, etc. In more psychological and philosophical terms, all concepts are symbolic in nature, and representations for these concepts are simply token artifacts that are allegorical to (but do not directly codify) a symbolic meaning, or symbolism.

Color or colour is the visual perceptual property corresponding in humans to the categories called red, yellow, blue and others. Color derives from the spectrum of light (distribution of light energy versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. Color categories and physical specifications of color are also associated with objects, materials, light sources, etc., based on their physical properties such as light absorption, reflection, or emission spectra.

Cool Color

Cool colors are blues and greens and everything in-between. These colorshave a calming effect and represent comfort and nurturing. Purple, even though it contains the hot color red, is also considered a cool color. Cool colors give off a quiet feeling that can make a person feel more relaxed and restful.

Warm Color           The colors of red, orange, and yellow are considered warm colors because they are the colors of fire. These hues are also said to advance, meaning they appear to come forward, making the walls feel closer. Thus, they can actually make a room feel cozy when used in decorating.

Hue is one of the main properties of a color, defined technically, as "the degree to which a stimulus can be described as similar to or different from stimuli that are described as red, green, blue, and yellow,".

Saturation is one of three coordinates in the HSL and HSV color spaces. Note that virtually all computer software implementing these spaces use a very rough approximation to calculate the value they call "saturation", such as the formula described for HSVand this value has little, if anything, to do with the description shown here.

The saturation of a color is determined by a combination of light intensity and how much it is distributed across the spectrum of different wavelengths. The purest (most saturated) color is achieved by using just one wavelength at a high intensity, such as in laser light. If the intensity drops, then as a result the saturation drops. To desaturate a color of given intensity in a subtractivesystem (such as watercolor), one can add white, black, gray, or the hue's complement.
