Greeting card of a colour theory illustration. Printed in England on a light cream, 300gsm carbon-neutral Italian paper, made from 100% recycled post-consumer waste. Adapted from Rose Synoptique (1890) by Charles Lacouture. Lacouture was a keen colour theorist and attempted to use three primary colours to create all hues, not by varying the tint of the inks, but by changing the density of intersecting and parallel lines. All our greeting cards are 170mm x 120mm (approx. 5” x 7”) and blank inside, individually wrapped in a compostable wrapper made from plants, with a 100% recycled, 110gsm kraft envelope.
