I am gradually creating downloadable colour charts for all the pencil ranges that I sell. The idea is for you to print them out and colour them in yourself - in your own style and technique - in order to create a library of reference charts for creating your coloured pencil art.
Caran d'Ache Charts
Supracolor Soft Aquarelle Pencils
Derwent Charts
Faber-Castell Charts
Albrecht Durer Watercolour Pencils
