Red Book 19 of series Details Red is one of the three primary colours. Mixed with blue it becomes purple and with yellow it makes orange plus many variations between depending on the proportions of each colour mixed together. With the addition of black and white to create shades and tints an enormous choice can be assembled. Within the colour circle, the opposite and complementary colour to red is green. In many of the sketches and samples shown, green is evident and acts as a foil to highlight and show red to great advantage. Equal amounts of the two colours can result in a pulsating effect as often seen on Christmas wrapping paper. The other primary colours of yellow and blue are complementary to purple and orange respectively. Soft cover, 25 pages. Price: $34.90 ($31.73) Contents: back
