Watercolour pencils work very differently to wax-based or oil-based pencils. Though they share a name, watercolour pencils don’t work in the same way watercolour paints do either. When it comes to watercolour pencils it is much better to use fewer layers of colour because heavy layering can lead to a sludgy buildup. More often than not pencil marks will remain on your work after you’ve applied water. These marks can be helpful for adding texture to your work and is a defining feature that separates it from watercolour paints. Additionally, watercolour pencils will dry quicker than watercolour paints which means you have to work at a faster pace.
