Unison Colour was founded by artist John Hersey who, after many years of not finding a pastel he was happy with, decided to make his own. 

Unison are a soft pastel, of a professional quality, they are handmade in the UK using the finest of materials. Still made using Hersey's original recipes, with a high pigment load, a huge choice of colours in a soft pigment loaded pastel stick. 

Unison Pastels are considered one of the best pastels in the world today.
