The full hue title or symbol may now be written as follows: (1) hue name, (2) amount of chroma, (3) value. Examples: GB¾D-V½HL. We are now in a position to write whatever color we may have in mind and another person will understand it, provided the other person adopts our standard. Through the teachings of Dr. D.W. Ross, Mr. A.H. Munsell, and others, the symbols and standards are now quite generally understood and have, in a slightly modified form been accepted in several standard color industries.
Technical Practice
Warm and Cold Colors
To familiarize oneself with the mixing of the various hues, it is excellent practice to form a vertical gray scale of the three-quarter-inch squares. There should be nine steps from white to black; an enlarged duplication of the right boundary of the hue rectangle. The warm standard hues at their full standard intensities; RV-R-OR-O-OY-Y, may be formed and placed opposite their gray equivalents on the left side of the gray scale, while the remaining or cold colors may be similarly placed with relation to the gray scale but upon the right of it.
Scales of Color
A vertical scale of tints and shades of one of the hues, duplicating the left side of the rectangle gives the character of the tints and shades. One shade and one tint should then be carried along a horizontal value line through three steps of loss of chroma to complete grayness, but without change of the original value. Yellow, by the addition of black becomes a false greenish shade which may be corrected by the addition of a small amount of vermilion.
Wood Stains
A large percentage of natural wood hues are to be found between the hue rectangles, Red-Orange, Yellow and Green, or in the warm portion of the spectrum. As a wood stain must blend harmoniously with the natural wood color, it is reasonable to expect the best results from stains with a predominance of warm hues or warm grays in their composition.
Basic Primary Hues
It is possible to duplicate nearly all the twelve standard hues of [Figure 455] with mixtures of the three so-called primary hues of red, yellow, and blue. It makes a fairly approximate scale which is, however, not sufficiently accurate for standardizing purposes. The scale is formed by mixing red and yellow in varying proportions for the intermediate hues of orange, yellow, and blue for the greens, and blue and red for the violets. This practice of mixing three primary colors together serves as an important step, governing wood stain mixing for beginners.
