Colourfix is a superb surface for acrylics, inks, silverpoint, oil pastels, gouache & watercolours. The colours are lightfast & the natural toothy surface will hold multiple layers of pastel without the need for fixative, allowing the velvet bloom & vibrant pastel colours to be preserved. Erasing is easy & the tough toothy surface can be sanded, scrubbed, soaked & re-worked over & over.
