MICROPOINTILLISM THEORY AND TECHNIQUE EXPLAINED

Color Theory of Micropointillism

     Microscopic specks of the primary colors yellow, red and blue on a white surface are all my paintings consist of. The viewing eye does the mixing of the thousands of colors that appear.

     Primary Color Micropointillism is the technique I use. It is a microscopic variation of Pointillism — the theory and technique of painting practiced by the likes of Seurat, Signac and other Pointillist painters of late 19th century France. Instead of creating colors by mashing pigments together on a palette and spreading them on canvas, the Pointillist painters dabbed masses of individual “points” of pure unmixed colors.

     These points blended by the eyes of the viewers to appear as many different colors depending on the amount and distribution the dabs. At a distance side-by-side blue and yellow dabs gave rise to the illusion green, yellow and red, to the illusion of orange. The Pointillist painters could use up to twenty distinct colors.

    Primary Color Micropointillist paintings use only, as the name implies, the three primary colors of yellow, red and blue atomized to microscopic size points by spraying. To the normal eye the colors of a Micropointillist painting appear solid. However, viewing through a pocket 30-power microscope will reveal that all colors are merely tiny yellow, red and blue dots in varying densities.

    The result is a brilliant skin of paint less than 1/100 of an inch thick with white being simply a hole in the skin, the white surface upon which the paint lies. The super-thin color results in a unique and intense luminosity as light easily passes through the thin skin to illuminate the color from behind.

    How is this achieved? I like to joke that it takes longer to explain Primary Color Micropointillist painting than to do one. So if you are ready to go into the weeds about how they are made, the following demonstation and documentary video will describe the technique and history of the Primary Color Micropointillist painting technique.

 

Technique of Micropointillism Demonstrated - The Painting of "Detroit Winter"

A micropoint painting begins with a drawing on a white gessoed surface. In this case it is canvas.

The first color, yellow, is then applied in stages.

[1] A liquid mask [silk screen block-out which appears purple here] is brushed on where yellow is NOT wanted or where enough yellow has been added. For example, what will be the pure white sunlit snow or warm chimney smoke is masked first so no yellow will fall on those areas.

I like to describe Micropointillist painting as 'backward painting' because you brush where you do NOT want paint or don't want any more paint. 

The brush strokes to the finest hairs appear making it appear as if the paint was brushed on. Instead their ghosts are preserved by the paint that surrounds them once the mask dissolves away. If you put a piece of masking tape on a board, spray painted it and then pulled it off, you would get the idea.

Obviously this requires understanding how much yellow is needed to combine with red and blue to make the desired colors for various areas.

[2] When the masking solution dries, a light spray of yellow paint is made over the entire surface of the painting falling on both the masked and unmasked areas.

The canvas is further masked and another light layer of paint is sprayed.

This process of masking and spraying is usually repeated as much as six to twelve times.

With each new masking additional parts of the painting are shielded leaving the remaining unmasked areas to become darker yellow.

The canvas is then hosed down water causing the maskings to dissolve away and revealing the painting in shades of yellow plus white (in the areas that were masked before any yellow was sprayed).

[3] The red phase is in progress. Mask is being applied. Red is being sprayed on between maskings.

[4] Actual painting, the applying of the color, is the easy part of Micropointillist technique. The exposed are areas are evenly sprayed until a point is reached where some part of the painting needs to be masked so that it gets no more red.

[5] Another easy part of Micropointillist painting is mixing the paint. Only three colors need be mixed to the consistency of milk. 

In this painting I used cadmium yellow, quinacridone violet [being mixed here and which is more of a magenta than a violet], and phthalocyanine blue as my primary colors.

Over time these have evolved as the best combination due to the rich intensity of each color but other variations of the three primary colors can work.

A 30 power pocket microscope [in green and white box] is used to occasionally inspect density of the micropoints of sprayed paint.

[6] The masks of the red phase are ready to be washed off. Only the areas of the most dense red remain unmasked.

[7] The water-soluble mask is dissolved away, mostly by hosing it away with some sponge scrubbing to remove any stubborn spots. 

The colors which are locked inside durable and waterproof acrylic medium are unaffected.

[8] Once the red phase mask is washed off, the structure of the painting becomes distinct. Masking of the final blue phase will follow. 

Any color that is to remain purely as seen here will be masked first. Pure whites like sunlit snow will be will be among the first. The second house on the left which will be green will get sprayed blue until the level of green appears, then it will be masked.

White is a given, the color of the gessoed canvas. Since those areas are masked first in each phase, white is 'hole' in the painting, as in watercolor painting.

[9] Midway through the blues. The painting will soon become a purple blue mess from the increasing densities of blue and the purple masking solution.

Excess spray paint is drawn through a furnace filter covering a box fan into a trap bag. As the vehicle for acrylic paint is water there is no issue of toxic fumes. However care must be taken not breath in the atomized paint particles which is accomplished by using a high quality face mask and venting the excess spray particles through filter traps.

[10] The blue phase a few maskings and sprayings later. The white clouds of the sky are masked and a blue sky with a touch of yellow to lean it in the aqua direction will emerge.

 [11] Ready for Splashdown! After hosing and sponging the balances of the three primary colors will create the full spectrum of colors of the painting.

One never quite knows the mood of the painting that will suddenly appear. I liken it to the birth of a child. We know the child will have fingers, eyes, arms and legs. But we can have no idea of the child's personality.

This is always a dramatic moment. The repeated application of the dark masking solution and spraying of the blue paint has transmuted the painting into a purple green mess.

Suddenly, from the murky chaos, the painting blossoms into its full spectrum of colors as the water streaming down the canvas carries away the dissolved masks. This moment has been dubbed the "splashdown".

It is a true "unveiling" of the painting as both artist and onlookers see the completed work in its full color brilliance for the first time. While there is a vision of what the painting will be final appearance is always a bit of a surprise. I liken it to the birth of a child. You know it will have hands, legs, eyes and fingers, but you cannot know it personality.

Micropointillism Defining a Medium by Nicolas Boileau

     Micropointillism was co-developed by Lowell Boileau and Stephen Goodfellow in the late 1970's and early 1980's in Highland Park, Michigan, USA.
