Chapter 13: Color

Now try overlapping shapes with some color.

 Example 7

How can Shading Effect a drawing ?

Light and shadows visually define objects.

You know the objects around you are three dimensional cause you can walk up them, see them from all sides, and touch them.

Addictive Color System?

A color mixing system in which combinations of different wavelengths of light create visual sensations of color.

What is Hue ? 

A property of color defined by distinctions within the visual spectrum or color wheel. 

Red, blue, yellow, green are examples of hue .

What is the value of color ?

Color value refers to the lightness or darkness of the hue. Adding white to a hue produces a high-value color, often called a tint. Adding black to a hue produces a low-value color, often called a shade.

Intensity of Color

Also called chroma or saturation, is the brightness of a color. A color is at full intensity when not mixed with black or white - a pure hue. You can change the intensity of a color, making it duller or more neutral by adding grey to the color. You can also change the intensity by adding its complement (this is the color found directly opposite on the traditional color wheel). When changing colors this way, the color produced is called a tone.

Cooler Colors - A color closer to the blue on the color wheel.

What is Color Dominance ?

Color Dominance is the principle of a composition that causes the viewer to be initially attracted to the emphasized color.  Every colored art composition portrays color dominance in some way. There are several different ways that a color can be dominant:

Camren Stacy Photography. North Carolina. 2011

              -A color is used in the most prominent area of a composition, 

              -A color is next to other colors which causes the most contrast,

              -A color is the most vibrant, OR    

              -A color occupies the most area in a compositon. 

Like regular dominance , Color Dominance can have a dominant, subordinate , and accentual colors .

What are Complementry Colors ?

Complementary colors: A color scheme incorporating Opposite Hues on the color wheel. These colors Accentuate each other in Juxtaposition and neutralized each other in Nature.

What are Triadic Colors?
a color scheme involving three Equally spaced colors on the color wheel.

What are Color Discords?
Is a perception of Dissonance in a color relationship.

Chapter 12: Value

Photoshop has a simple way to show Value.

Example 6

What is The definition of Value?
A measure of relativer lightness or darkness.


VALUE SCALE



When you think about the Value of Contrast -
It is the Contrast between our lightest and darkest values.  (According to Albert Munsell who developed much of the visual color theory we use today), the dark to light scale - he numbered the colors 1-10 , 1 being black and 10 being white.

Value Patterns 
Good compositions are generally an arrangement of three or four shapes.  Incorporate the principle of dominance. In order for a picture to have a design it must have value differences or simply light and dark masses that produce a "Value Pattern". Using only 3 values, the following basic value patterns are among the possibilities.

A dark Shape against mid-tones.
A light shape against mid-tones.
A large dark and a small light against mid-tones.
A large light and a small dark against mid-tones.
A graded value pattern.
A checkerboard pattern.

Value as Emphasis?
Some situations call for strong visual dominance such as attracting the viewer's attention to the main subject of an image. Some situations call for more subtle emphasis such as leading the viewer through the composition and directing them to a secondary focal point. The designer should be able to use all levels of control over the viewer's attention. This includes the ability to put something in an image that may escape detection for a long time (and then be a delight to find).

There are three major methods for controlling emphasis in a visual image: contrast, placement and isolation.


Chiaroscuro?
an Italian word that means 'light-dark'.  In Paintings the description refers to clear tonal Contrasts which are often used to suggest the volume and modeling of the subjects depicted.

Giovanni Baglione. Sacred and Profane Love. 1602–1603,

 showing dramatic compositional chiaroscuro

Leonardo was fasinated by the atmosphere and by its effects on the colors and distinctness of distant objects.Though some begun to crete some of these effects in their work , leonardo was the first to make 

these measurments. He called the subject Arial Perspective

Thus if one is to be five times as distant, 

Make it five times blurr.
