|The Difference between
"Mixing" and "Visual" Complements
BY HILARY PAGE
Most artists know that complementary color pairs can be used for two functions. These are (1) for color mixing- to make clear colors more neutral and (2) for visual color enhancement- to make juxtaposed saturated colors appear even more brilliant. Most artists, however, are misinformed about the actual colors of complementary colors pairs. So read on! This information could change the way you paint!
|The red Amarylis flowers appear particularly vibrant because they are surrounded by the VISUAL COMPLEMENT of red which is Turquoise blue green.|
before I began to research color I realized that specific pairs of colors
mutually enhance one another. This was because in my youth in England
when I used to paint color coordinated plaster pixies to sell for extra
pocket money, I found that certain combinations such as blue and yellow,
were particularly pleasing. These same color pairs are what I now call
"visual complements" though I didn't call them by that name in those days!
My later experience as a painter, and research for my books led me to question the prevailing literature on the subject. It gradually became clear to me that there are not just one set of complementary color pairs but two sets. These are required for the two separate functions of color mixing and color enhancement. The colors of the two sets are definitely not the same though most artists are unaware of this. How about you! The good news is that if you use the right visual complements, the color in your paintings will be more exquisite and dazzling than ever before.
|Lemon yellow appears much more vibrant when surrounded by its "visual" complement which is blue. Most artists erroneously pair yellow with purple for color enhancement which is related to the way the eye works (lateral inhibition and disinhibition). I coined the names "mixing" and "visual" complements to describe the two functions of the two types of complementary pairs of colors. Hilary Page|
|So let's take a moment here to get down to the basics. A complement is "that which completes". What do MIXING and VISUAL complements complete that makes them fundamentally different? "Mixing" complements complete the subtractive color mixing process. "Visual" complements complete the optical synthesis which is bound by the way our eyes work. Thus I coined the names "mixing" and "visual" complements to describe these two processes.|
|"Mixing" complements, used for color mixing are pairs of colors that neutralize one another as an increasing amount of one is added to the other. i.e. green neutralizes red as increasing amounts of the green are added to the red. The actual color pairs are determined because they complete the subtractive color mixing process in which the amount of reflected light from a painted surface is subtracted with each admixture i.e. you paint gets darker! The right pairs (yellow/purple or red/green or blue/orange) will produce BLACK or a VERY DARK GRAY when mixed in the correct proportions. Mixing complements are usually placed opposite one another on the color wheel.|
complements used for color enhancement are pairs of colors
that make each one appear more vibrant when they are painted contiguously.
i.e. blue will appear more vibrant if juxtaposed by yellow. (Color enhancement
is an aspect of the phenomenon known as simultaneous contrast, related
to how the eye works.)
The actual color pairs are determined because they complete the optical synthesis in which the eyes equalize reflected light from a painted surface when viewed. Only the right pairs will produce a COLORLESS GRAY when painted in the correct proportions either on a disc and spun, or as dots as in Pointillism. Fortunately we don't have to go through this arduous process! Ogden Rood in his book "Modern Chromatics" (1879) named the correct colors of the complementary pairs that he named "contrast colors". The color pairs have been quantifiably established by Ellen Marx in her incisive book "Optical Contrast & Simultaneity" (1983 Van Nostrand Reinhold Company Inc). Note: Ellen Marx does not use the term visual complements to describe the phenomena. I determined the corresponding pigments that I have listed below in the vertical chart. You will need to use precise colors for optimal color enhancement. Note that the colors of "visual" complements correspond to the colored "light" complements that complete the additive synthesis of adding colored lights. The right pairs when shone together yield WHITE light.
Here are the color pairs that I use for color enhancement. . If your favorite color is not listed, find the nearest visual complement that you can find! It is important to use the precise paints listed to achieve optimal color enhancement. Thus I have used the color index name such as PY175 (included on paint tubes) so that you can match the exact paint listed no matter which brand you are using. The brands that I have used are Winsor & Newton, Daniel Smith and Holbein paints. Click here to link to WCO'S manufacturers' page.
|THESE ARE THE COLORS OF VISUAL COMPLEMENTARY PAIRS|
mistake in not distinguishing between the colors of MIXING and VISUAL
complementary color pairs dates from the start of the nineteenth century.
Color-contrast was already an established principle and the term "complement"
was first used for so called color harmony and afterimages. Johann Wolfgang
von Goethe, the prolific German author, stated in his "Theory of Colours"
(1810) that for "completeness" the eye produces a "complemental hue upon
each color". This is not the same meaning as understood by a "complement"
in today's art. (The after image effect to which he refers relates to
a phenomenon known as successive contrast). Goethe also asserted that
a mixture of all colors made gray. He designed a triangle of three "complemental"
pairs using the same color arrangement as Moses Harris who created the
first artists' color wheel in 1776 designed specifically as an aid to
color mixing. Harris mixed three "secondary" colors- green/violet/orange/-
from the primary colors red/yellow/blue/ and placed them oppositeone
another, with BLACK in the center. Referring to both of these charts,
many artists then used the same opposite colors both for color
enhancement and also for color mixing, thus erroneously combining the
colors of MIXING and VISUAL complements for the two separate functions.
The confusion was sustained by Michel-Eugene Chevreul , a French chemist and color theorist who, unlike Goethe, did indeed understand the difference between subtractive and optical/additive color. In his book "The Principles of Harmony and Contrast of Colors and their Application to the Arts"(1839) he offered a wheel showing complementary pairs and specifically stated that this was for color modification "upon the eye", and not for paint mixing. However, since he used the same colors pairs as Goethe, he continued the error of not distinguishing between "mixing" an "visual" complements. For instance, he used red/green instead of red/ turquoise, blue/orange instead of cyan/orange, and yellow/violet instead of yellow/blue for color enhancement. These color combinations were then erroneously used by many of the French Impressionist painters as well as fashion, garden and interior designers of that period and to this day.
Ogden Rood in "Modern Chromatics" (1879) named the correct "visual" complementary contrast colors- pairs that he called "companions" that when juxtaposed glowed "with more than their natural brilliancy". Unfortunately, he failed to articulate that there was a difference between "visual" and "mixing" complements. And so the confusion continued- until today when I hope this article has sorted out the mess for you!

Now I hope you enjoy working through the demonstration below on using "visual" complements. Remember that you do NOT mix visual complements. You use them to make saturated or pure colors as brilliant as they can be! Hilary Page December 3rd. 2006
|LEMONS ON BLUE DEMONSTRATION:
A STUDY UTILIZING VISUAL COMPLEMENTS
BY HILARY PAGE
is a demonstration from start to finish in which I have used a visual
complementary pair of colors- yellow and blue for color enhancement: I
juxtaposed the yellow lemons with their visual complement, blue, to make
the lemons appear especially brilliant.
This Lemons on Blue study is easy for you to duplicate at home or in your studio. All you need are a dozen or so fresh lemons, a couple of blue cloths, possibly a lemon squeezer and a knife, and hey presto! You can paint along!
I used a quarter sheet (11X15") Arches 140Ib cold pressed paper and the following Daniel Smith paints: Hansa Yellow Light (PY3)
Hansa Yellow (PY97)
Cobalt Blue (PB28)
Ultramarine Blue GS (PB29)
French Ultramarine RS (PB29)
Quinacridone Rose PV19r
carefully arranging my lemons and cloths by a north facing window I made
a credit-card sized value sketch by squinting to help me see the value.
I then did a line drawing to scale on sketch paper which I subsequently
transferred to my watercolor paper using a light table. I don't like to
photograph and trace off a drawing since this does not allow for creativity
and improvisation, and anyway it's too boring!
I next squeezed out blobs of paints in three separate palettes for my blues, yellows, and grays. I mixed the grays from Cobalt Blue, Quinacridone Rose and Hansa yellow light. I put about a teaspoonful of water in each palette. To complete by preparations, near where I was working, I placed an absorbent cotton towel on a board that was a little larger than my watercolor paper. You'll see why soon!
|I hope you have enjoyed this step by step study for visual complements. There are many more such demonstrations in my books "Watercolor Right from the Start" and "Color Right from the Start" and as here, each one illustrates a different aspect of watercolor painting or color theory.
