COLOR DEMONSTRATION


Long ago I created this tiny pastel sketch of a church. I called it “Burning Church” for obvious reasons and filed it away.


Years later I was playing with ideas for “landmarks” along Broadway in New York City, and realized that my “Burning Church” might work on a site at the north end of Manhattan on 170th Street.

In designing the church I ran with a simplified gothic style with a blank base raising the sanctuary above the street level.


I then built an Autocad 3D model and tried out a number of viewpoints. This hidden line view was chosen for the final drawing.


This magic marker sketch gives a preliminary idea of the values I was aiming for.


A base drawing was produced using freehand ink on mylar.


The final drawing was 30” x 40”, so there was plenty of room for detail and texture.


Reproduced above is a color wheel. It shows the full range of colors going around the circumference, with saturation going from the center of the circle (desaturation = grey) to full color saturation at the circle edge. This is fully discussed on the outstanding “Gurney Journey” blog. 



The original “Burning Church” sketch uses a very tight range of yellows and browns marked by the diamond shape of the color wheel. The sketch derives its strength from the limited palette.





The last color sketch above and accompanying color wheel show a complimentary palette ranging from yellow to blue. The combination of color contrast and value contrast makes the tower pop out strongly.





The last color sketch above and color wheel show an orange to grey-green palette. The color contrast is less strong, and the value contrast is created with a tower running from light on dark at the bottom to dark on light at the top. I’ve always loved the red-orange contrast with a grey-green sky; it reminds me of a portrait trick of contrasting warm flesh against a grey-green background.



The two sketches above have low saturation color palettes. Essentially, they are low contrast grey studies with pastel tone here and there.



The strong blue and yellow sketch above is going in the right direction, but seems a little bit too simple.


By adding a graded reddish tint top and bottom I pushed the focus to the center of the tower suggesting a cross composition


The sketch above was done full size with pastel and pencil to study the detailed coloring of the church entry.


 And here is the final art (30” x 40”). Note the darkened foreground and sky which adds to the drama and makes an excellent background for the white line elevations and plans. The final was done with transparent ink airbrushed on a photographic print of the ink line drawing. The title was done with white acrylic applied with (tiny) brushes. The ghosted plans/elevations/sections and quotes were color pencil.

Inspiration - Waterhouse & Color



John William Waterhouse was a Victorian era painter (1849 – 1917). Both his father and mother were English born artists, and so his professional path should not have been a surprise. Born in Rome, he returned to England with his parents while still a child, and eventually spent the remainder of his life in London. Although early on he was interested in Engineering, he did not follow that profession, but began working in his father’s studio. His father, curiously, did not want him to become an artist, but was eventually persuaded to help John enter the Royal Academy. At the age of 21 Waterhouse was accepted into the Academy as a student in sculpture, but instead of attending classes, he practiced and perfected his painting technique by continuing to work in his father’s studio. Yes, that sounds like a lot of contradictions and “U” turns, but in the end he showed genius that was recognized in his own time.


Sketch of Waterhouse for The Bank and Royal Exchange by W. Logsdail 1886
Many of the specific events of Waterhouse’s career are unknown because his wife, who survived him by several decades, destroyed much of his correspondence. However, we have his paintings, which can be read and studied to good effect. Waterhouse is an unlikely inspiration for an architectural illustrator in that he was a painter’s painter. He preferred to illustrate ancient myths in a figurative, realistic and painterly way, relegating the built environment to the background. And he created his images in a layered adjustment of opaque paint, which is a technique anathema to the detailed and transparent tradition of architectural rendering.


In spite of this, Waterhouse offers many clues to the handling of color and drama that can be applied to architecture. For instance, the oil sketch above, done for the painting The Love Philtre shows the development of a careful balance between red-browns and green-browns, with the composition being held together by the strongly contrasting flesh tones. 


The Lady of Shalot is one of Waterhouse’s most famous paintings. It depicts the despondent Lady Elaine, who loved Sir Lancelot in the Arthur legend. Lancelot’s rejection of her love drove her to despair and death. The picture seems perfectly balanced and harmonized, but there is a palpable sense of despair in every part of the canvas.
This detail shows the wide range of colors that he has placed in the focal point of the painting. Note that the pure colors of the fabric are limited to relatively small spots, while the contrasting orange-browns dominate. The background consists of dull greens, and the figure is revealed in variations of white.


Ophelia, one of a series of paintings on the Shakespearian subject, is simple in composition, but complex in its expressive use of color. The almost black trees suggest the madness that is coming with Hamlet’s rejection of her. Her supine position suggests her watery grave, and the inverted face suggests her world, which has been turned upside down by Hamlet’s madness.
Waterhouse’s use of contrasting color insures that in spite of the centralized composition, the viewer’s eye will be drawn to the warm face and burning hair of Ophelia, enhanced by the surrounding green. Note that he flirts with a strong yellow-green, but always moderates it with olive and brown.


This detail of Waterhouse’s painting, Sweet Summer, illustrates his ability to moderate colors so as to emphasize the composition. In other hands the green of the grass, along with the red and blue of the dress would dominate the painting. Indeed, in the modern world the clash of primary colors would be “de rigueur”.


Similarly, in The Crystal Ball Waterhouse moderates the red dress so as to let the swirling composition animate the scene. The repeating arcs, suggesting the crystal ball of the title are brilliant.


I’ve always found the death of Orpheus to be a rather curious tale. A severed head which floats down a river and over the sea to the island of Lesbos, singing all the way strains credulity (and induces hilarity), but that’s myth for you. The reason for including this painting, Nymphs finding the Head of Orpheus, is once again to note the carefully modulated colors. As before, they form an undertone to the more obvious, and again, swirling composition. 


Cleopatra is a painting that reverses his usual “light on dark” composition, with the queen’s head as a dramatically dark spot on a lighter field. On the other hand, it is very typical in terms of color; the light “field” is made up of a number of different colors which are harmonized and “dulled” so as to set off the darker hair and face.


Here is another Ophelia by Waterhouse. In this rendition he emphasizes the madness that is rising in the girl, and foreshadows the death that awaits her by drowning in the river at her feet. The color handling is much moderated, especially in the lower part of the dress where the red and gold seem to melt into the grass and tree trunk.


Circe, in the Odyssey, is a witch who turns men into swine. In Waterhouse’s conception she is a mixture of seduction and danger rendered in a beautifully amorphous fabric which conceals and reveals mysteriously. This painting is less clear in its composition then his other paintings, but that is in keeping with the subject.


The Toilet is a painting with no ancient myth or truth to convey, but it is a lovely study in browns and greens (with the touch of blue in the foreground). Waterhouse could have allowed the colors to dominate more in this composition, but still, the effect is charming to the viewer, and illuminating to the student.


Mariamne, the beloved second wife of Harod the Great, was falsely accused and convicted of attempting to murder Harod. In this painting she is pictured going to her death, while Harod, who still loves her, grieves. On first glance the painting seems to be monochromatic, but as usual with Waterhouse, it has considerable color in a muted form.

Resting is another domestic scene with less drama and compositional strength. It is included here to reiterate the delicate color sense that Waterhouse brought to his work. It is also typical of the overcast light that Waterhouse favored in all his paintings.


Of all the settings shown in this post, this is the most directly applicable to architectural illustration. The martyred Saint Eulalia is shown in a snow scene which lets the subtle colors and forms of the classical buildings stand out. Note how the colorless marble shifts from cool grays to warm grays throughout the painting.

And the moral of the Waterhouse oeuvre? That color needn’t be garish and bright, but can be powerful even when muted. Also that muted color can strengthen a good composition. An important point to remember is that Waterhouse justified his muted palette by choosing a diffuse light, and the rejecting the brilliant, direct sunlight. Modern architectural illustration, and especially computer rendering tends to default to direct sunlight because of the simplicity of layout and efficiency of the process. But, using diffuse light and overcast conditions can produce amazing results.

Natural Spotlights



Not long ago I was on a bench in Washington Square Park people watching. It is one of the better places in New York City to see the entire spectrum of humanity mingling on the urban stage. The sun was low in the west, and streamed into the square between the buildings on the west side of the park. This created a tight “spotlight”, making the area beneath the Garibaldi monument something of a stage.

The effect of “spotlights” is dramatic. It takes the scruffy street musician, and makes him into an event. While an urban “spotlight” such as that shown above is created when buildings block the sun, the same effect can be created by clouds on a grander scale.

The photo above of Providence Town shows a sunset spotlight highlighting the beach front. It is subtle, but charming. The unlit buildings to the left and right frame the view. Note that the edges of this “spotlight” are soft, whereas the spotlights at Washington Square were relatively sharp.

This computer tablet sketch uses the same effect to emphasize the part of the town with the church steeple.

The same effect is illustrated in Berthing Boats in a Dutch Harbor by Andreas Achenbach, painted in 1877.

Newburyport Meadows by Martin Johnson Heade shows the source of the spotlights that are playing across the meadows.

The Cactus Friend by Carl Spitzweg suggests how dramatic the spotlight effect can be, even when used in the simplest sketch.

This illustration (Babe’s Greatest Moment by Douglas Crockwell), may not seem to have anything to do with architectural illustration, but it is a blueprint for drama. Imagine a cluster of buildings lit by the rays of a sunset cutting in beneath the grey blanket of a thunder storm.

One occasion an illustrator can use a large fuzzy spotlight is in highlighting a specific part of an urban scene in an aerial perspective. LaCledes Landing could not be seen without the context of downtown St. Louis, but it had to stand out from the rest of the urban fabric. A very soft sky spotlight was used which shows everything in perfect detail, but gives the new development the starring role.

Die Propyläen auf dem Münchner Königsplatz Leo von Klenze is a beautiful example of soft and hard shadows. The soft edged shadow the makes the top of the structure lighter than the bottom is produced by the clouds that are miles away. The sharp shadow to the left of the entry is cast by the portico itself which is perhaps 15 feet away. The edges are soft or hard depending on the sharpness of the thing blocking the sun, and on the distance between the object where the shadow is cast and the object blocking the sun. Since the sun’s disc is not a point, the edge of a shadow becomes fuzzier in proportion to the width of the sun’s disc and the ratio of the distance from the casting object and the sun, and the casting object and the shadow.

Besides the sharpness of the edge of spots, the color of the light and the color of the shadow are important in getting the effect right. Note that the shadow cast by the girl is sharp (because she is close to the shadow), and cool compared to the lighted stone. This is because the major light striking the shadowed area is blue light reflected from the sky. The shaded cracks of the stone below her elbow are a warm brown/grey because they are primarily lit by light reflecting up from the surrounding stone.

Spotlights are an easy (and surprisingly forgiving) tool for producing drama. Try them out whenever a bit of emotion and showmanship is called for.
