It's called "Colourfix" because this very permanent, lightfast coated paper withstands all manner of artistic experimentation. Art Spectrum Colourfix Original Coated Pastel Paper has a medium toothy surface that will hold multiple layers of pastel, charcoal, or chalk without needing fixative between the layers. The absence of fixative allows the velvet bloom and vibrant color of pastel to be preserved.
The unique, surface is produced by screen printing Art Spectrum Colourfix Primer onto a heavy weight Hot Press watercolour paper. The 140 lb (300 gsm), acid-free surface will also withstand sanding, scrubbing, soaking, and being reworked. These papers are used successfully in practically all media — pastels, charcoal, pencil, oils, acrylic, gouache, inks, silverpoint, and even watercolour.
