These colours are specially formulated to provide one coat coverage on most surfaces. The formula varies slightly from the standard palette colours as they include fillers to smooth out imperfections for ease in basecoating. Colours are independently tested and conform to AST lightfastness standards to ensure they will not fade over time.

Use in conjunction with Jo Sonja mediums for various effects and techniques. They are suitable for most surfaces including wood, paper, cards, illustration board, canvas and terracotta pots.
