MATCHING CHART.
The following color chart is used by some trimmers for matching colors. As already explained, the modern window calls for a variety of colorings, and it is in the matching of these colors, such as the compound shades, drabs, buffs, sages, with their different hues, that considerable work and patience is called for. With such colors as these a number of points are to be considered before a definite conclusion can be obtained. Some of the shades, for example, are very sensitive to the various qualities of daylight. A dark, cloudy day, a sunny, bright day, a hazy day, etc., all have their effect upon the colorings in the window design. There are other conditions which come in to interfere with the proposed color adjustment of the window trimmer.
Colors may appear so and so to the eye when placed in the design with certain other colors. A blue setting, for instance, may match each other if the combination includes several shades of blue. When the design is placed in its place in the window, alongside of a yellow, for example, the yellow offsets certain of the blue shades, producing tints of a yellowish green of some of the blues, while blueish greens are developed in others. This, of course, disorders the proposed color plan and the result is discouraging unless it is known how to overcome or avoid such troubles. Furthermore, certain colors which match by daylight are made quite the reverse as soon as the electric light or the gas light is turned on in the window. All this is perplexing to the window artist, but there are remedies. Use charts 1, 2 and 3. In the first are the standard color chart line, A, B, C, D, E, F, G and H. These represent the color lines of the solar spectrum. Along the side of the chart are figures 1, 2 and 3. The first indicates the absorption spectrum of yellow color. By following the chart lines it will be seen that this yellow absorbs violet and blue, while it transmits red, green and yellow. In 2 we can see that the blue which this division represents absorbs orange red, yellow green and yellow, and transmits blue, violet and part of the green. Division 3 represents green, which results as a combination of the two former divisions.
In Fig. 2 is a chart for representing the absorption of ruby glass and a single green shade. In this it can be seen that division 1 involves transmission of the red in A to the orange red in C, and the remaining colors are absorbed. In 2 is an absorption of all the colors except green, yellow green, blue and blue violet. In 3 is the result of combining the colors, in which case this setting permits no rays to pass, resulting in full black or darkness. In chart 3 is another plan for color setting in which 1 indicates the absorption spectrum of yellow, 2 in which violet shows the absorption in yellow and yellow green, 3 the compound of green rays with the absorption of the remainder of the spectrum.
