A color model (Or color system) is a way to describe colors based on certain characteristics such the color's Red, Green and Blue levels... or its hue, value, saturation... etc.
Hue, Value and Saturation color model
Three qualities, or properties, Hue, Value and Saturation, may be used in combination to describe any color. HUE"Hue" has been previously covered. |
|
|
 |
Note:
The hue, Magenta, is a mixture of red and blue wavelengths... It is an extra-spectral color, meaning it is not within the visible spectrum as generated by a single wavelength of light.
Magenta's relationship to other hues may be shown on a color wheel.
VALUE
| Value is the relative lightness or darkness of a color. This is a middle-value gray. |  |
|
| This gray is higher in value than the middle value gray; but lower in value than white. A painting using values as light as, or lighter than middle value gray would be referred to as "High Key." |  |
Diebenkorn |
| Lower in value than the middle value gray; but higher in value than black. A painting using values as dark as, or darker than middle value gray would be "Low Key" |  |
Daumier |
| Value is the relative lightness or darkness of a color. These three colors... made from different hues, have approximately the same value. |  |
|
SATURATION
| Saturation is the purity of a color. Intensity is another name for saturation. These three colors, also made from different hues, have approximately the same saturation. Notice that the value of the blue is lower than the othe two colors. |  |
| This is violet at full intensity... fully saturated... "pure." |  |
| Less pure colors are "subdued" |  |
| Completely subdued colors are "neutrals." |  |
| Internationally famous :-) artist Allen Cosgrove used intense colors in this image. |
 |
| Robert Indiana used almost pure/highly saturated hues in this painting. |  |
| Landscape of subdued colors ~ Monet. |
 |
| Figure study using subdued colors ~ Thomas Dewing |  |
| The same Dewing, artificially intensified |  |
| And more intensified. |  |
| A mixture of ONLY Black and White will result in an Achromatic Gray. Achromatic grays have no hue and no saturation... only value |  |
| Achromatic grays in Stieglitz' photograph |  |
| A mixture of a small amount of a hue plus Black and White will result in Chromatic Gray. Chromatic grays exhibit a subtle, but discernible hue... they are minimally saturated. |  Two scales of chromatic grays. |
Cosgrove ~ Chromatic Grays |

Giger ~ Achromatic Grays |

Mixing hues with black and/or whitewill usually change the value and will always lower the saturation |
||
| Tint: Hue plus white. The value will always become lighter than the pure hue and the saturation will be lowered. |
Tints of orange hue |  |
| Assorted Tints |  |
|
| Tints are used in William Trost Richards painting |  |
|
| Shade: Hue plus black. The value will always become darker than the pure hue and the saturation will be lowered. | Shades of orange hue |  |
Assorted Shades |
 |
|
| Shades in Winslow Homer's painting |  |
|
| Tone: Hue plus black and white. The saturation will be lowered and the value will change toward the value of the gray that was added. | Tones of orange hue |  |
| Assorted Tones |  |
|
| Tones in Balla's painting |  |
|
Complementary and Broken Colors |
|
Complementary colors are two colors that are directly across from each other on the color wheel. For example, Red and Cyan are complementary colors on this cmy color wheel.
|
 |
| When mixed together, complementary colors neutralize each other and become a dark gray or brown. |  |
Broken Colors result from the unequal mixing of two complementary colors... in this case, the complementary colors are mostly red with cyan addded. |
 |
| These are assorted broken colors... a pure hue with some of its complement added. |  |
Assignment
Bring in sketchbooks next Tuesday, 4/11.
Paint a saturation/intensity/value scale as shown in the drawing below… CUT OUT and use 1” squares of Bristol Board... mount it on a larger sheet.
Sketchbook - on 3 separate pages
- Find examples of colors as pure hues and glue them into your sketch book
- Find examples of subdued colors and glue them into your sketch book
- Find examples of neutrals or nearly neutrals and glue them into your sketch book.
Examples may be photos, magazine clippings, web photos, wallpaper samples, house paint samples, etc.
Bring in sketchbooks next Tuesday, 4/11.
