Elements of Design - ValueBy Joao Rodrigues and Joshua Kim

Value refers to the relative lightness and darkness of a certain area. Value is used to emphasize elements that are part of the picture/drawing.
Focal point is created by variations in value, making the picture more appealing. A light figure on a dark background will be more noticeable than if both were the same color.
Value can also be used to create the illusion of depth and volume. Light areas that are shaded by a darker color will give the impression of a three-dimensional image, making it more eye-catching.

Categories of Value

Tint is when white is added on to a color to make it have a lighter value, for example light green.
1) Shade-Tint Wheel

Shade is when black is added to a color to create darker values, for example dark blue.
2) Shade Color-Wheel

A picture is high-key when all values are light.
A picture is low-key when all values are dark.

3) High- and Low-key Value Ranges

Value contrast happens when a light color is put next to a dark color making it contrast.

4) Value Contrast is being used in this image to emphasize the vegetation

Value scale is the scale that shows the gradual change in value from its lightest value, white, to its darkest value, black.

5) Example of a value-scale

 Tonal Contrast

It is the difference between bright and dark areas in a painting or drawing.
The greater the contrast between these areas, the greater amount of attraction that it will receive from viewers.

6) Example of how a tonal contrast between sections creates a strong attraction to a viewer If the value range is reduced, the tonal contrast still remains even though it's impact is reduced.

7) In this image of a fly, the tonal contrast between the lightness reflected on the fly and the darkness of the background, cause attention to go immediately to this area.
