Understanding Color  Chapter 4: The Vocabulary of Color
The three qualities of     color are:•Hue• Value• Saturation
RedGreen  BlueYellow       Hue means  the name of the color.
In science, the colors of light are called            spectral colors.
Spectral colors can be measured precisely bytheir different wavelengths (or frequencies.)
The words “hue” and “color” are often       used interchangeably.
In everday speech (including ourtext book), the word “color” isused in two different ways.It can mean:It can mean:• the HU...
The word “hue” should never, however,be used to mean anything other than the            name of a color.    Chroma is a sy...
Chromatic: having hue
Achromatic: without hue
Polychromatic: having many hues
Monochromatic: having one hue only
It has been theorized that the average person candistinguish about 150 colors of light and every one can    be described u...
Red

Yellow
Green
Blue
Violet
YellowYellowYellow        Yellow A color is called by the name of its  most obvious, or dominant, hue.
Nearly all colorsamples include morethan one hue, butone hue is mostapparent and othersare present in smallerproportion.
A sample mayseem to be pure yellow until it isplaced next to a different yellow          sample.
Suddenly, one  yellow is seen to    contain a bit of green, the other afraction of orange.
Both are called yellow because         yellowpredominates in           each.
Using the word“contains” helps toevaluate colors.
“This yellowcontains someorange.”“This yellowcontains somegreen.”
The artists’spectrum is a      circle thatillustrates huesin their natural       (spectral)          order.
The spectrum of visible light (additive color) islinear and is displayed according to wavelength.
The artists’spectrum is alsofixed in its order ofcolors, but it has sixhues instead of sevenand they arepresented as acont...
The artists’spectrum is alsocalled thecolor wheel orcolor circle.

...so the artists’spectrum is asort of visualoutline, orsynopsis, of allvisible hues.
The basicspectrum ismade up of sixhues: red,yellow, blue,orange, green,and violet
The expandedspectrumincludesyellow-orange,red-orange, red-violet,blue-violet,blue-green, andyellow-green.
The artists; spectrum is limited to six or twelve huesonly because this is a concise, easily illustrated figure.
It can be expanded to any number of hues as long as the added colors are inserted at regular intervals in                 ...
Color wheels come in all types...
But they all recognize the same sequence of colors.
All color circles include the primary hues in some     way, and all follow the same color order.
A chromatic scale is any linear series of hues in              spectrum order. Each step in the progression is a change in...
The words “cool” and “warm” are used to describe         two opposing qualities of hue.
Warm colors are reds, oranges, yellows, and the            steps between them.
Cool colors are blues, greens, violets, and the steps                  between them.
The primary colors are weighted toward the warm.
Only blue is cool, while both red and yellow are               considered warm.
As a result, the entire spectrum is more heavily            “warm” than it is “cool.”
Blue is the polar extreme of cool, and orange, made  of red and yellow, is the polar extreme of warm.
Warmth and coolness in colors are not absolutequalities. Any color, even a primary, can appear  warmer or cooler relative ...

Analogous colors are hues that are adjacent on the                artists’ spectrum
They are described in various ways.
For the purposes of this class, analogous colors are simply colors that are next to each other on the                   co...
And while it is true that the most harmoniousanalogous groupings are made up of even intervals of                         ...
...all analogous color schemes achieve a sense of                     harmony.
The text book claims that they never contain all            three primary colors.
But when you expand your analogous color schemes to include hues that contain the third primary–as long as thecolors are n...
Remember that     analogy is not  confined to pure            colors.  Colors that havebeen diluted in any   way can also ...
Complementary colors are hues that areopposite one another on the artists’ spectrum.
Together, the two are called complements, or a            complementary pair.
The basic complementary pairs of the artists’              spectrum are:
Yellow and violet
Blue and orange
Red and green
In each of thesepairs, one half is aprimary color andthe other half is thesecondary that is amixture of theremaining twopr...
It is important to note that the threebasic complementary pairs are different  from each other in how much they        con...
Because the complements vary in value,their contrast is more or less accordingly.
Red and green
Orange and blue
Yellow and violet
Othercomplementay  pairs are less     contrasting  because eachcolor containsone primary in common with   its opposite.
For instance, red-violet and yellow-green           each contain blue.
No matter what thevalue or saturation of acolor, it maintains atall times acomplementaryrelationship with itsopposite.
Ignore your book on    the subject of   tertiary color!
For the purposes     of this class,    tertiaries are  colors that are mixed with their    complement.
There are aninfinite amount ofcolors that can be      produced by     mixing colors         with their      complement.
As you can see, many tertiary colors resemble the color wecall “brown,” and others approach the color we call “gray.”
But remember that brown and gray are not hues.
Black, gray and white are achromatic -        meaning “without color.”
Absolute blacks and whites exist only in the             medium of light.
In subtractive media, blacks and whitesalways have some colorant that gives them a              suggestion of hue.
True grays, or mixtures of black and white,          are also achromatic.
Subtractive grays are characterized as either               warm or cool.
Value refers to the relative light and dark in                  a color.
Hue iscircular andcontinuous,but value islinear andprogressive.
Value exists whether or not hue is present.
The colors of the artists’ spectrum (or color       wheel) have different values.
White is the lightest possible value, and black is thedarkest possible value. All other colors fall somewhere             ...
Only value contrast   makes objectsdistinguishable from their background.
The degree of contrastbetween light and dark areas determines the   strength, or graphic   quality, of an image.
Differences between form and their background may be further emphasized by contrasts of hue orsaturation, but difference i...

However, high contrast images are not always desirable.   Strong contrasts of dark and light induce lateral         inhibi...
One of the defining characteristics of a line is that it         contrasts with the background.  (The other is that it is ...

...but the thinnest of contrasting line between them           creates an immediate separation.
The placement of different values relative to oneanother within an image give it individual identity.
In order to transpose an image from one color toanother, the number and placement of values within the                imag...
Value is also associated with the idea of luminosity. A   hue that is luminous reflects a great deal of light,            ...
The artists’ spectrum illustrates colors at evenly spacedintervals of hue, but not of evenly spaced intervals of value.
A tint is a hue that has white added to it.
A shade is a hue that has black added to it.
A tone is a hue that has gray added to it.
This is different than in your text book.   Take notice!!!
A monochromatic value scale is a singlehue illustrated as a full range of values in even    steps, including both tints an...
Any hue can be illustrated as a full range of tints  and shades, from near-white to near-black.

It is easy todetermine valuedifferences ingray scale butmuch harderwhen comparingvalue in a hue.
It is especiallyhard whencomparing valuesin two differenthues.
Even complementswith the highest huecontrast can be made unreadable bymanipulating thevalue.
Saturation (or chroma)refers to the hue intensity.
A saturated color is a color at its fullest expression   of hue. It is a color at maximum chroma.
Saturation is acomparativeterm. Itdescribes thecontrastbetween dulland vivid.
Saturation, like value, is linear and progressive.
The beginning of a saturation scale is a color that is hue-intensive. The end step is a color so dull         that its hue...
Although they are sometimes mixed up, saturation    is a color quality that is distinct from value.
Shades are already reduced in saturation because they contain black, so it is instinctive to think ofmuted colors as dark....
One way to do this is to mix a hue with a gray of the same value. This is what we call a “tone.”
When white ismixed with a hue, it           changes      saturation.     It also changes              value.
When black ismixed with a hue, it           changes      saturation.     It also changes              value.
When gray is mixed     with a hue, it           changes      saturation.  But it does NOT    change value.
Another way to reduce the saturation of a hue is to              add its complement.               +                 =
Another way to reduce the saturation of a hue is to              add its complement.

  91. 91. The closer in value an image is to itsbackground, the harder it is to see.
  92. 92. However, high contrast images are not always desirable. Strong contrasts of dark and light induce lateral inhibition, and can fatigue the eyes.

  131. 131. Keep in mind that this point is subjective and can be different for different individuals. ?
  132. 132. The term “theoretical gray” is used in thetext book to indicate a concept used by color theorists to characterize a perfect tertiary color: one of no discernible hue.
  133. 133. In theory, there should be a middle point between all complements that is the same. But in practice, it does not exist.For the purposes of this class, theoretical gray is the same thing as achromatic gray.
  134. 134. Some of the most interesting colors result from mixedcomplements that have been tinted to raise their value. These are the light neutrals you see in many consumer goods.
  135. 135. The exuberance of saturated color is easily found innature, but muted colors are by far the greatest part of our visual world.
  136. 136. And remember, that it is the CONTRAST between these different qualities of color that draw our attention to them.
