Successive Contrast. 
"The successive contrast of colors includes all the phenomena which 
are observed when the eyes, having looked at one or more colored 
objects for a certain length of time, perceive, upon turning them 
away, images of these objects, having the color complementary to 
that which belongs to each of them." 
If we look steadily at any color for a time, and then immediately 
look at something white, the eye will perceive the contrasting effect 
of the color looked at. As this color effect succeeds the positive im- 
pression, it is called Successive Contrast. 
Mixed Contrast. 
"The distinction of simultaneous and successive contrast renders it 
easy to comprehend the phenomenon which we call mixed contrast; 
because it results from the fact that the eye, having seen for a time a 
certain color, acquiring an aptitude to see for another period the 
complementary of that color, and also a new color presented to it by 
an exterior object; the sensation then perceived is that which results 
from this new color and the complementary of the first." 
By the foregoing it will be seen that every color effect is modified, 
favorably or otherwise, by associating other colors with it. Thus, if 
black and blue are associated, the complementary of blue, that is, 
orange yellow, is cast upon the black, which gives it a rusty appear- 
ance. In like manner the complementary of the color looked at, is 
always projected upon the neighboring surface, and affects its color 
more or less. 
Both Successive Contrast and Mixed Contrast are but variations of 
Simultaneous Contrast. 
Harmonious effects in color combinations are produced in various 
ways, and depend not only upon the different colors that aie used in 
the combination, but also upon the quantity and intensity of each 
color used. 
For the purpose of elementary instruction Mr. Henry T. Bailey 
has placed all of the harmonies under the following divisions: 
Contrasted Harmony. 
Dominant Harmony. 
Complementary Harmony. 
Analogous Harmony. 
Perfected Harmony. 
This is, however, simply an arbitrary classification, and is useful 
only so far as it helps to simplify the presentation of the subject to 
beginners. 
Contrasted Harmony is an agreeable combination of any color or 
tone, that contrasts with white, black, gray, gold or silver. 
Dominant Harmony is an agreeable combination of colors produced 
by using the different tones of one color scale. 
Complementary Harmony is an agreeable combination of colors pro- 
duced by using complementary or opposite colors. 
Analogous Harmony is an agreeable combination of colors pro- 
duced by using those colors that are related to a common basal color. 
Perfected Harmony is an agreeable color effect, produced by using 
colors in such proportions that their admixture will produce, or ap- 
proximate white, (gray).
