Political colour which dates back to the French Revolution in the 18th century and the revolutions of 1848. Before this nascence, the colour red was generally associated with monarchy or the Church due to the symbolism and association of Christ's blood. The colour red was chosen to represent the blood of the workers who died in the struggle against capitalism. All major socialist and communist alliances and organisations—including the First, Second and Third Internationals—used red as their official colour. The association between the colour red and communism is particularly strong. Communists use red much more often and more extensively than other ideologies
Orange (colour) Winslow Homer brightened his palette with vivid oranges. In France painters took orange in an entirely different direction. In 1872 Claude Monet painted "Impression, Sunrise", a tiny orange sun and some orange light reflected on the clouds and water in the centre of a hazy blue landscape. This painting gave its name to the impressionist movement. Orange became an important colour for all the impressionist painters. They all had studied the recent books on colour theory, and they know that orange placed next to azure blue made both colours much brighter. Auguste Renoir painted boats with stripes of chrome orange
