Line can be considered in two ways. The linear marks made with a pen or brush or the edge created when two shapes meet.
A shape is a self contained defined area of geometric or organic form. A positive shape in a painting automatically creates a negative shape.
Value is the lightness or darkness of a colour. Value is also called Tone
Texture is the surface quality of a shape - rough, smooth, soft hard glossy etc. Texture can be physical (tactile) or visual.
Color is the response of the eye to differing wavelengths of radiation within the visible spectrum.
The simplest definition of shape is a closed contour, an element defined by its perimeter. The three basic shapes are: circle, rectangle (square) and triangle
PRINCIPLES OF DESIGN
Balance in design is similar to balance in physics.
Repetiton with variation is interesting, without variation repetition can become monotonous
Relating the design elements to the the idea being expressed in a painting reinforces the principal of unity
Areas of interest. Guides the eye into through and out of the image through the use of sequence of various levels of focal points, primary focal point, secondary, tertiary, etc
- Contrast-Contrast is the occurrence of contrasting elements, such as colour, value, size, etc. It creates interest and pulls the attention toward the focal point.
the recurrence of elements within a piece: colours, lines, shapes, values, etc. Any element that occurs is generally echoed, often with some variation to keep interest.
in interior design also may be used to reduce randomness. For example, placing four plant pots in a row and evenly spaced apart on a floor produces an organized look.
The use of dissimilar elements, which creates interest. Variety like a painting or some reflective wood panels added on a plain wall may be used to reduce monotony. Helps infuse color to a house decor to attempt to increase design beauty.
