Coloured pencils are no longer just for children - more and more adults and hobby artists are discovering them as a relaxing leisure activity and creative means of expression. Designing colouring books is a trend that helps many adults to leave everyday life behind and immerse themselves in the world of colour. But free drawing and colouring are also popular leisure activities. There is a choice between waterproof and water-soluble coloured pencils. Watercolour pencils are coloured pencils that can be mixed with water after the paint has been applied, making them ideal for mixed media. The tip of the watercolour pencils can be used to draw precise details, which can then either be painted with water or left as a coloured pencil drawing.
