Below there is a color chart in which I have illustrated the intermixture of the three primary pigment colors, RYB (red, yellow and blue), using the three primary print colors CMY, (cyan, magenta and yellow) excluding black, (K). The addition of black, (K), is necessary in the printing process in order to equal out the contrast of value and add depth to the color range. I have excluded blacK from this color chart to illustrate the pure range of color mixtures. In this color chart, I have illustrated the intermixture of the complementary colors on the color wheel. This color chart combines both pigment complementary intermixtures with the compliments used in photolithographic printmaking. It also shows the percentage of intermixtures between each of two complementary colors and the grayscale gradating from 100% black to 100% white. I used this scale of measurement to illustrate that gray remains 50% whether you are analyzing light or pigment or ink. When working with light, black being the absence of light equals 0% and white equals 100% or 255 when working with Photoshop. When working with pigment the reverse is true. Black equals 100% and white equals 0%. Thus, light mixtures are additive and the mixture of pigment is subtractive simply because when you add colored light the result is more luminous but when you add colored pigment the result is always increasingly more muted. An equal mixture of all three primary pigments equals a very dark grey which is almost black while an equal mixture of all three primary colors in light equals a brilliant white light. |

When working with pigments, yellow, especially when placed on a dark ground is the most luminous of colors. Because stained glass is actually colored light, RGB, (red, green and blue), its properties are quite different. Cobalt blue is the most luminous color in a stained glass window. Note how the black matrix of the epoxy holding the glass together surrounding the yellow in the window below is easily seen, and how the black matrix surrounding the intense blue is dissolved in its halation. |
7 Contrasts of Color as put forth by Johannes Itten
1a). Hue Contrast;
- observed differences designated by name; Cadmium Yellow, Hansa Yellow, Lemon Yellow, Yellow-Orange, Lilly White, Salmon, etc. - Importance of Knowing our Subjective Timbre
2b). Value Contrast or Light to Dark;
- use of White is necessary but minimal use of Black is preferable - Do I lean toward the Dark, the Light or in-between? The Complementary pair of Violet & Yellow is the most intense Value Contrast.
3c). Temperature Contrast or Cool to Warm;
- Blue & Orange is the most intense Temperature Contrast and the pair is also Complimentary. (Picasso used such a palette during his blue period) but this same palette can be used to create an orange period, hypothetically; a predominantly orange painting...
4d). Complementary Contrast;
- Opposites on the color wheel and most intense color contrasts; - All color harmony hinges on this; ex. remove 1 of the 3 primary colors, Red, Blue, and Yellow, ex. (Red) isolated from the opposing complementary combination of remaining 2 primaries, (Blue & Yellow when mixed resulting in green, the complement of Red) and with intermixing of White into all of these color combinations results in a broad range of Color Hues, Values, Cool to Warm, Saturation and of course the Complementary Contrast, indeed, all of the main, applicable color contrasts. The Complements Blue - Orange is the most intense Temperature Contrast, the Complements Violet - Yellow is the most Extreme Value Contrast - the Complements Green - Red are, perhaps, the most intense Contrast in Vibrance.
5e). Saturation Contrast or Intense Color to Muted Color;
- Power and Depth, from the transient and mundane to the sublime - this is the progenitor of fine art - this is what the palette is for - a shadow of this principle/contrast has been achieved by a very few throughout history - no one has ever come close to a complete mastery of this color application of art with the possible exception of Claude Monet and notwithstanding the multitude of unknown masters.
6f). Simultaneous Contrast;
- when colors affect each other simultaneously - Relativity into Action; It is the psychological - physiological tendency within us to perceive 2 adjacent colors, in different regions of the color wheel, in such a way that they appear to become more pronounced, that their specific natures become more enhanced to the extent that a gray that leans toward a cool-blue takes on an increased intensity of blue when a dull, burnt sienna is placed next to it. And the dull burnt sienna takes on an enhanced appearance of being more orange simultaneously. A dull red will make an adjacent dark muted yellow seem lighter, brighter and greener; in turn, the former will appear darker, more intense and more blue-violet.
6f.b). Successive Contrast;
- Similarly, after viewing a color, esp. a vivid color for an extended period of time; and then when we look away, the afterimage is the opposite in value, temperature, saturation and complement, and the cause is to restore the psychological - physiological balance within our means of perception.
7g). Extension Contrast;
- The playground of color fields, contrasts of proportion, area, space, value, complements, and color intensity optically inducing movement; (causing the eye to bounce around the page), causing the color contrasts to become more pronounced, etc., balancing saturated color with muted color.
The color chart below is an illustration of the intermixture between the three primary light colors and their opposites, (complements). A complement is simply an equal combination of the two primaries left over when one is isolated. On the top left, red has been isolated from the three. On the top right is shown the compliment of red which is an equal intermixture of green and blue. Green and blue produce cyan. When green is isolated, its complement is an equal intermixture of red and blue which produces magenta. And when blue is isolated, its complement is the result of an equal intermixture of red and green which produces yellow. An equal mixture of all three primaries produces white in the center. |
The logic behind the use of cyan, magenta and yellow as the three primaries in the photo-lithographic printing process is that they are the compliments or (opposites) of the three primaries in light. Since the one primary color in pigment, (yellow) is substituted for its equivalent primary in light, (green), and since without yellow it is impossible to achieve the full range of color mixtures using ink or pigment, through many years of arduous experimentation the formula of cyan, magenta and yellow was devised.
Printing inks are translucent and lose their chroma when printed on anything but white paper. Because it is also impossible to achieve 100% black and in effect, anything beyond 70% gray, the addition of blacK, (K) has been introduced into the photolithographic printing process. Therefore the four color process of cyan, magenta, yellow and blacK, (CMYK) was developed.
Below are four grayscale charts illustrating the differences between the mixture of RGB, CMY, CMYK and blacK only. The first grayscale was done with blacK only in quantity of ascending order from left to right. The next grayscale was created using equal percentages of RGB color in descending order from left to right. Note how the blacK grayscale is equal in value only to the RGB grayscale. The CMY grayscale below that is pale in comparison and retains some color that leans towards magenta. The CMYK grayscale below that retains some color and the gradation is not in equal steps as are the blacK and RGB grayscales. The three grayscales below that are the same as the three above them except they have been converted from RGB mode to grayscale mode in photoshop. |
Statement of Purpose:
My purpose is simply to share with those who are interested, my own personal views on the subject of art and design. While I am acutely aware that my opinions are not, by any means universal, I have had some modicum of hands-on experience with the subject.
It is my primary intention to shed some light on the complexities of artistic composition. Art doesn't just happen. The creation of a painting, sculpture, work in stained glass or print can be excruciatingly painful on mental, emotional and spiritual levels. |
