BLUE VIOLET 



Color Photography Explained — 1 



In order that a clear understanding may be gained of the 

 process emploved in making prints on paper, such as are used 

 in these volumes, a series of nine prints will be shown here. The 

 first of this series, appearing above, shows the primary colors, red, 

 green and blue-violet, and opposite, these are their complementary 

 colors, often incorrectly called the primary colors, blue-green, pink, 

 and yellow. Colors are said to be complementary to each other when 

 their separate rays combine to make pure white light, A 

 further explanation of the employment of these colors 

 will be found in the captions of the suc- 

 ceeding pictures of this series.
