Use same color scale as in chart of values (red). Mount one-inch squares. Then taking the middle value of the hue red, decrease it in chroma or intensity by mixing it with its complement blue-green 5 until it becomes neutral 5. Next mix red 5 with blue-green 5 until its chroma is half way between neutral 5 and red 5, thus making R of middle value and middle chroma. The result may be tested with the Munsell middle color cards. Then, combine red with its complement to form intermediate chromas between the middle chroma and gray, and intermediates between middle chroma and red 5 (diagram, Fig. 31). By adding water or Chinese white, increase the value of the three intermediate chromas; and by adding black decrease the values; complete the chart according to Diagram 4. This may be simplified by omitting the value scale of chromas. Fig. 32 is another suggestion for a chroma chart.

We should now understand the three dimensions or qualities of color, hue, value and chroma. The next step is to recognize and become more familiar with them.
Whatever system of notation is chosen it must be clearly understood and consistently adhered to. Munsell gives the following:
Hue is notated with the initial letter; for example, red, R, blue, B, etc.
Fig. 31. - Chroma chart.
Value is indicated by a numeral placed above the line to the right of the initial. Thus R5 means red at 5 of the value scale.
Suggestions for exercises in color design.
Chroma is shown by a numeral below the line, thus R means red of value 5 and a chroma one-half way between a full intensity and gray. In the chroma scale we have used only five steps. In order to keep them consistent with the value scale of nine steps we number them according to the diagram (Fig. 32).
