I recently bought 6 Unison pastels in the colours of red earth and pastel red. These are for a special painting I'm planning and I chose Unison colours because I always find that the colours are 'spot on' and you can always find the colour you want within the unison range. The texture and softness of these pastels is a delight to use. These days Unison pastels are a natural choice for me. Heather B
