Visual Problems in Value
Introduction:
“Value is simply the artistic term for light and dark. An area’s value is its relative lightness or darkness in a given context. Only through changes of light and dark can we perceive anything”.
—Design Basics, Chapter 12
Application:
The following exercises and project are designed to give the student both short-term and long-term experiences in creating lights and darks--value. Four individual exercises require students to explore the relationships between light and dark as well as the relationship between value and color. One culminating project encourages students to synthesize various important concepts of value such as emphasis and space. Students render their value projects in a professional manner with media used in the field of design, including the computer. The final results are critiqued by their classmates and by their instructor.
Traditional Media
Using regular sketching paper make an eight-step value scale from dark to light. Each value step should be one inch square. Various drawing pencils may be used, i.e., a 2B or 4B pencil creates a dark value, whereas a 2H or 4H pencil creates a light value. Using a Master Card-type design (see diagram), render as many black and white (positive or negative) options as possible. You cannot change the design of a rectangle with two overlapping circles. You must fill in shapes with black and leave the remaining area(s) white with each attempt. There are sixteen variations.
Begin with a rectangle of either a vertical or horizontal proportion. Next, draw into the rectangle six straight horizontal or vertical lines. The lines may overlap or not depending on the individual design. No two areas in the composition can be the same size. Now render the rectangular shapes in white, black, and middle values. Using pencils make even applications of these values.
Start with the same rectangular design with lines similar to exercise 3. This time make a dark, middle, and light valued design, but with the concept of "key". Key refers to the overall lightness or darkness of a composition. Either render these three values in "high key" or in "low key". Special note: The three values will be closer together than was the case in exercise 3; but you must still establish a dark value and a light value with a "mid-way" value in between these two values.
Electronic Media
Using Adobe Illustrator or Adobe Photoshop, make a ten to twelve step value scale from dark to light. Each value step should be one inch square. Print out scales to see how well the values hold their distinctiveness in print. Compare the results with their appearance on the monitor.
Using Adobe Illustrator or Adobe Photoshop, create as many black and white designs as possible utilizing a Master Card composition as shown in "Traditional Media, number 2. You cannot change the design of a rectangle with two equal overlapping circles. You must fill in shapes with black and leave the remaining area white with each try. Note: draw one design and copy it each time to create a possible black and white design. There are sixteen possible variations.
Start with a rectangle of either a vertical or horizontal proportion. Using Adobe Illustrator or Photoshop draw into the rectangles either horizontal or vertical. The rectangles may overlap or stand alone. No two areas of the composition can be the same size or proportion. Next, render the resultant shapes in white, black and middle values. Print the results.
Begin with the same rectangular design made for exercise 3. This time create the same design, with dark, middle, and light values, but with the concept of "key". Render this design either in "low key" or "high key". Special note: The three values will be closer together than was the case in exercise 3; but a dark value and alight value with a mid-way value between the two must be established.
Project:
Goal: To create a vertical or horizontal landscape design in which atmospheric perspective creates an illusion of depth.
Materials:
A. Traditional design media that will be employed in the execution of this project.
Illustration or bristol board approximately 12"x15".
Black drawing ink and white opaque water-based paint.
Two watercolor sable brushes, one chisel and one rounded.
Drawing pencils and tracing paper
B. Electronic design software such as: Adobe Illustrator or Adobe Photoshop. Project can be designed and rendered either with traditional media or electronic (computer) software. It is also possible to mix traditional and electronic media. For example, a student could use traditional media in drawing original images and utilize Adobe Illustrator to create multiple horizontal planes for use in the project.
Guidelines:
An illusion of depth must be created through the principle of strong value contrasts in the foreground and subtle value contrasts in the background.
Overlapping horizontal planes in various gradations of sizes, from large in the foreground to small in the background, can be used to create the overall pattern of perspective.
A focal point created through the principle of value contrast should be created in the foreground of the landscape design.
A wide range of "key", or values, should be used in the landscape composition.

1. Give an example of local color. Why is it considered local?
2. List the 5 Basic Color Schemes or color harmonies and briefly describe them.
Glossary
Additive system A color mixing system in which combinations of different wavelengths of light create visual sensations of color.
Afterimage Occurs after staring at an area of intense color for a certain amount of time and then quickly glancing away toward a white surface where the complementary color seems to appear.
Analogous colors A color scheme that combines several hues located next to each other on the color wheel.
Chroma See Intensity.
Color constancy A psychological compensation for changes in light when observing a color. A viewer interprets the color to be the same under various light conditions.
Color discord A perception of dissonance in a color relationship.
Color harmony Any one of a number of color relationships based on groupings within the color wheel (see Analogous Colors, Color Triad, and Complementary).
Color symbolism Employing color to signify human character traits or concepts.
Color triad Three colors equidistant on the color wheel.
Color wheel An arrangement of colors based on the sequence of hues in the visible spectrum.
Complementary A color scheme incorporating opposite hues on the color wheel. Complementary colors accentuate each other in juxtaposition and neutralize each other in mixture.
Composition The overall arrangement and organization of visual elements on the two-dimensional surface.
Constancy effect An aspect of human perception that allows us to see size, or color, or form as consistent even if circumstances change appearances.
Cool color A color closer to blue on the color wheel.
Emotional color A subjective approach to color usage to elicit an emotional response in the viewer.
Hue A property of color defined by distinctions within the visual spectrum or color wheel. Red, blue, yellow, and green are examples of hue names.
Intensity The saturation of hue perceived in a color.
Local color The identifying color perceived in ordinary daylight.
Monochromatic A color scheme using only one hue with varying degrees of value or intensity.
Opaque A surface impenetrable by light.
Optical mixture Color mixture created in the eye as small bits of color are perceived to blend and form a mixture.
Pointillism A system of color mixing (used in painting and drawing) based on the juxtaposition of small bits of pure color. Also called divisionism. (see also optical mixture)
Primary colors The three colors from which all other colors can theoretically be mixed. The primaries of pigments are traditionally presented as red, yellow, and blue, while the primaries of light are red, blue, and green.
Saturation See Intensity.
Secondary color A mixture of any two primary colors.
Simultaneous contrast The effect created by two complementary colors seen in juxtaposition. Each color seems more intense in this context.
Spectrum The range of visible color created when white light is passed through a prism.
Subtractive system A color mixing system in which pigment (physical substance) is combined to create visual sensations of color. Wavelengths of light absorbed by the substance are subtracted, and the reflected wavelengths constitute the perceived color.
Tertiary A mixture of a primary and an adjacent secondary color.
Tint A hue mixed with white.
Tonality A single color or hue that dominates the entire color structure despite the presence of other colors.
Tone A hue mixed with its complement.
Transparency A situation in which an object or form allows light to pass through it. In two-dimensional art, two forms overlap, but they are both seen in their entirety.
Triadic A color scheme involving three equally spaced colors on the color wheel.
Vibrating colors Colours that create a flickering effect at their border. This effect is usually dependent on an equal value relationship and strong hue contrast.
Visual color mixing The optical mixture of small units of color so that the eye perceives the mixture rather than the individual component colors.
Warm color A color that appears to be closer to the yellow-to-red side of the color wheel.
