Scaling. 
Ouantity Value Fr ° m th,S it: is evident that there is a quality value 
and a quantity value as well as an intensity value, and 
that it is very seldom that equal quantities of two or more colors can 
be used in a combination when we desire to produce a harmonious 
color effect. 
Scaling is the arrangement of colors in the order of 
their sequence, intensity, or variations. In addition to 
the scaling of the normal colors, there may be as many different 
scales as there are different hues and different variations in light and 
shade. Scaling may be by normal colors, by tones, by hues, or by 
these combined. 
A scale of normal colors consists of the regular arrangement of 
the normal colors in their prismatic order.

Scale of Tones of Blue. 
A scale of tones may consist of any number of different tones or 
intensities of the same color; but they must be arranged in the order 
of their sequence, from dark to light or from light to dark. 
The term tone covers all the variations of a color that can be 
produced by adding either white or black to the basal color, whether 
it be a normal color or a hue; but only one of these (either white or 
black) may be added, else it becomes a broken color.
