Color Theory: Harmony in Paintings

Why We Need Color Theory

Color theory is an immensely complicated subject, and is understood differently by scientists, printers, web

designers and painters. Subtractive color (where mixing the hues will create black) is what oil paintersgenerally use, and some grasp of the theory will help you understand:

1. Why some colors 'work' together, and others don't.

2. How paintings are designed: color is a vital element of composition.

3. The principles that have guided successful painters, and which are still useful.

4. How to mix colors if only very broadly: pigments have individual properties.

Hue, Purity and ValueColors are classified by three properties: hue, purity and value terms that are often misunderstood.Experimenting with a graphics program will get the distinctions into your head, though colors mix differently onscreen.

Hue

The intrinsic color; the wavelength of the light concerned. The strips shows primary, secondary and tertiaryhues.

Purity

The freedom from other color admixtures. Saturation is the degree of purity. Chroma is the purity inrelationship to gray. (N.B. Some authors also use intensity to mean color purity, whereas for others it meanstone/value.)

Value

The luminance brightness or dullness of a hue, as measured by the amount of light reflected. Also calledtone or tonal value.

A tint is made by adding white to a hue, and shade is made by adding black. As far as oil painting pigments areconcerned, mixing in white or black with usually lower the purity of a hue, making it chalkier or muddier.

Primary, Secondary and Tertiary Colors

Red, yellow and blue are the primary colors, which can't be derived from still more basic colors. Mixing twoprimary colors will create one of the s econdary colors: orange, green or purple. A secondary color mixed with anadjacent primary (on the color wheel) will create a tertiary color.

Color WarmthColors are also commonly described as warm or cold. Warm colors lie at the orange-red end of the spectrum,and are 'active', causing them to 'advance'. Blue colors, particularly when dark and/or undersaturated, are 'cool'

and tend to 'recede'. Other areas of the spectrum remain neutral.

Mixing ColorsColor theory provides a only rough guide only to mixing paints. In practice you will need to:

1. Experiment to learn the individual properties of pigments and their mixtures, probably making referencecharts to begin with.

2. Make more attractive tints and shades with colors other than white and black (e.g. light and dark earths).

3. Purchase pigments for the secondary and certainly the tertiary colors. Mixing primaries will only result in

muddy hues.4. Use glazes if you wish to modify colors without mixing them overmuch.

Color Harmony: ApproachesAs always, the important thing is to see for for yourself to study the great masterworks and experiment withtheir color schemes to understand what has been done and why. You can do that easily today by taking copiesof the work (scanning books or using Internet sites) and analyzing them with a cheap graphics program.

There are indeed many schemes for color harmony, but the following should be useful to the painter. Note thatthey apply only to hues: for variety you can (and should) vary the purity and tones of the hues concerned.

Monochrome

One hue. Composition is achieved entirely through adjusting purities and tones. A limitedbut powerful approach, that always makes a good exercise.

In this detail from his Diana and Callisto (1556-9. National Gallery of Scotland. Edinburgh),Titian has used a simple orange hue throughout, not far from that shown above in thecolor purity strip. The marvelous variety comes from modifying purity and tone with glazesand scumbles which demonstrates the power of old master techniques. (The wholepicture uses a wider color range, including blue and a pink-red.)

Complementary

Composition uses one hue and its complementary e.g. blue and orange. The hues can bemixed in various proportions, and tones added with white or black (or preferably earthpigments).

The detail comes from a famous painting by Monet of the Beach at Trouville (1870). It waspainted on the spot. Though seeming a careless, even clumsy, improvisatory sketch, it is

nothing of the sort. Monet served a traditional apprenticeship, and is here playing off an orange in beach andflesh tones against chalky tints of blue.

Analogous.


3/4



Composition using just 3 hues of 12-color wheel - e.g. orange, orange-red and red. Asbefore, the hues can be mixed, and their tones adjusted.

This scheme can be further divided into:

1. one pure hue and the other two semi-neutral (i.e. mixed, muddy, low intensity). Thepure tone will advance more than the others, whether is warm or cold.

2. high key pure hues. Usually applied in a broken fashion so that hues of the same value shimmer when seenclose to, but group to broad areas of color from a dis tance.

3. one dominant, one subordinate and one minor. The dominant is varied with different purities and values.

The detail is from Eugene Delacroix's Death of Sardanapolis . 1826. Muse du Louvre. Paris. The whole pictureemploys an analogous color scheme of red, red-orange and orange.

Split Complementary

Like analogous, but with the addition of the complementary of the mid-hue of theanalogous range. A warm/cool balance is more easily introduced with this scheme.

This intimate painting by Mary Cassatt ( The Bath . c. 1892. The Art Institute of Chicago)uses tertiary hues, and falls somewhere between a triadic scheme and a splitcomplementary one of red-purple against hues of green-blue. The background repeats theforeground colors but in muddier and darker colors.

Triadic

Uses all three hues that are equidistance on color wheel. Hues may be varied in purity andtone as usual, and the scheme is further divided:

1. Primary colors only: very difficult to use outside posters and graphic design.

2. Secondary triadics, e.g . scarlet, mauve and viridian. Very beautiful effects can beachieved, probably because all colors contain some of the other two secondaries.

Green, blue and yellow appear in this detail from Vermeer's The Music Lesson (c. 1664. HM The Queen's RoyalCollection. St. James's Palace). Harmony has also been achieved by very skillful use of tone.

Other ConsiderationsHarmony is also achieved by using colors of similar purity or tonal value. The harmony is not generally anexpressive one, however, and is more useful to industrial and graphic designers.

Practical ImplicationsAll paintings have color, and will not be successful unless some color harmony scheme is articulated. You willneed to:

1. select from the colors in the subject in front of you, or

2. emphasize certain aspects of the colors in front of you, or

3. impose a scheme of colors that does not occur in the subject

Some paintings will require a combination of all three strategies, but the implementation requires practice anda clear notion what you're trying to achieve.
