Vegan 100% Lightfast Oil-Based Coloured Pencils

Derwent Lightfast pencils have been formulated to be one hundred percent lightfast. The innovative core is resistant to colour change ensuring artwork will not fade under museum conditions for up to 100 years. These artist grade oil-infused pencils have smooth, velvety cores that put down solid, opaque colour and dry-mix well to create new colours. Offered in an array of vibrant colours and sets.

Every Derwent Lightfast Coloured Pencil satisfies the international lightfast testing standard, ASTM D6901 and Blue Wool Scale ISO 105. A scale of 1 - 5 is obtained with values 1 and 2 considered to be highly lightfast.

Rather than limiting your palette to the choices straight out of the tin, expand your colour range by tinting and mixing colours directly on the paper surface. This will create a more natural look to your work, and form a new and vibrant colour. The thick core of Derwent Lightfast allows for dense and even colour application.

Many people equate lightfastness with permanence. This is not strictly accurate as many other factors can affect the permanence of your work such as humidity, temperature, atmospheric pollution, reactions between different pigments and chemicals, the paper you use, and even the way you use your art materials. For optimum performance of your pencils follow these simple guidelines: 

• Use high-quality pH neutral heavyweight paper
• Create strong, even layers and avoid damaging the substrate
• Do not hang or exhibit your work in direct sunlight
• Mount your work behind glass, preferably with an ultraviolet absorbing coating
• Remember that the lightfastness of Derwent Lightfast may be adversely affected if mixed with other products
