Line - is a visual element that connects two points. It can be long or short, and it can also be thick or thin. It can flow in different orientations, such as vertical, horizontal, or diagonal. It can also come in solid, dotted, or dashed.
Vertical lines - these are perfectly straight lines that travel from top to bottom.
Horizontal lines - these are perfectly straight lines that travel from left to right.
Diagonal lines - these are perfectly straight lines that travel from top-left to bottom-right or vice-versa.
Curved lines - these lines are bent and are not perfectly straight.
Continuous lines - these are solid lines that travel from one point to another. They can be perfectly straight or curved.
Interrupted lines - these lines also travel from one point to another, but unlike continuous lines, they have gaps along the way. Dotted and dashed are common types of interrupted lines.
Implied lines - these lines are not technically drawn or created, but simply exist where one color or texture touches another.
Contour lines - these lines are used to define edges on an object. It creates the illusion of boundaries.
Dividing lines - these lines are also used to define edges, but unlike contour lines, they divide space. Common examples of dividing lines are those that separate columns in menu items and reading materials such as books and
magazines.
Decoration lines - these lines are commonly used to give a 2D element a volume. Cross-hatching is an example of a decorative line; it adds shades and forms to an object.
Gesture lines - these lines are continuous lines that portray the motion of an object.
Lines Stressing Words - lines are used to emphasize a specific word or piece of information.
Lines as borders - lines are also used to emphasize an element and separate it from other objects in the composition.
Lines in structures - lines can also be used to form a layout between elements. Lines in structures provide separation and decoration.
Color - Color is the visual perceptual property deriving from the spectrum of light interacting with the photoreceptor cells of the eyes. Color categories and physical specifications of color are associated with objects or materials based on their physical properties, such as light absorption, reflection, or emission spectra
Hue - in theory, is one of the main properties of a color. Most of the time, color and hue are used interchangeably. The origin of color is referred to as its hue. Primary, secondary, and tertiary colors are considered hues.
Value - refers to the lightness or darkness of a hue. It shows how the quantity of light is reflected on an object.
Saturation - refers to the vividness, richness, or intensity of a color.
Primary colors - are the base hues that form the color wheel. They are the Red, Yellow, and Blue.
Secondary colors - are hues that result when combining two primary colors. Green, orange, and violet are the
secondary colors.
Tertiary colors - are created by mixing a primary color with its nearest secondary color. Blue-green, red-orange, and red-violet are examples of these colors.
Monochromatic color scheme - is a color scheme that is a result of altering the base hue by adding white (tint) or black (shade).
Analogous colors - are three colors that sit next to each other on the color wheel.
Complementary colors - are colors that are located on the opposite side of the color wheel. These colors provide a high-contrast color combination.
Triadic colors - are colors that are located when you form a triangle in the color wheel.
Tetradic colors - are colors that are located when you form a rectangle in the color wheel. These scheme provides a dominant color, with the other colors working as accents.
Shapes - Are two-dimensional areas with recognizable boundaries. It can be organic or inorganic, free-form or geometric. These are recognizable and are defined by their color fill, outline, or the stroke that forms the edges.
Positive shape refers to the area of interest in a composition, such as the face of a subject or figure in a portrait, an object in a painting, or trees in a landscape painting.
Negative shape refers to the background or area that surrounds the main subject.
Geometric shapes - are what most of us think of as shapes. These shapes are composed of lines, curves, surfaces, and angles. Circles, squares, and triangles are some of the most common geometric shapes.
Natural or organic shapes - are shapes that are found in nature. These shapes are more curved and uneven, adding
interest and reinforcing themes.
Abstract shapes - are recognizable but are not real. They are stylized or simplified versions of organic shapes. Symbols are abstract shapes to represent ideas and concepts
Texture - It is a visual element that adds visual interest and depth to a composition. These can influence the look and feel of a graphic design work by adding a visual tone that attracts interest to an element depending on the texture used.
Image textures - are created from a combination of organic or geometric shapes and colors. It can be a variety of simple or complex shapes, randomly created for a particular look.
Environmental textures - can be formed by clouds, woods, and sand grains.
Pattern textures - can also be in the form of organic and geometric shapes and colors, but these textures are mostly manufactured.
Positive Space - refers to the area or part of the composition that equates to being the subject or focal point.
Negative space - refers to the area or part of the composition that is empty or an open space that surrounds the main subject.
Overlapping - occurs when an element appears closer to the viewer block or hinders part of another element.
