When trying to match the colours in the stone with water colours I was surprised at how bright the colours actually are. I mixed numerous shades and held them against the stone to find the best matches. I wasn’t particularly pleased with the water colour versions…the colours matched well but were not capable of showing the granularity of the stone.
Adding a layer of oil pastel over the top over the water colour helped to give a more grainy appearance which better represented the texture of the stone and the mixture of colours.

A better representation of the colours was achieved by using layers of oil pastel.
