    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).

                            ANALYSIS 
    Exercise 5.-Using varied illustrative material classify colors accord-

ing to hue, value and chroma-orally-students verify each other's answers.

    Exercise 6.-Memorize color by classification, that is, look at a color

for a minute and notate mentally-produce from memory-then compare. 
    Exercise 7.-Reproduce color from dictation. 
    Exercise 8.-Mix colors of various hues, values and chroma; record 
the results. Color Play. Value scales may be made of the most pleasing 
hues. 
    Exercise 9.-Using gradated colored paper samples select values, hues

and chromas from dictation. 
    All of these suggestions may be enlarged upon, making innu- 
merable short exercises and greatly increasing the interest in the 
subject. 
    Practice in color perception is most necessary, for upon it 
depends the training of the eye, which is the source of joy in color. 
The development of the faculty of seeing and feeling color repays
