ARTISTS' OIL COLOUR VANDYKE BROWN
Vandyke Brown is a brown pigment named after the Flemish painter Van Dyke who used it in many of his paintings. It is an earth pigment and is often used for shading.
Colour Index Name: Each pigment can be universally identified by its Colour Index Generic Name. As an example: Cobalt Blue is Pigment Blue 28, abbreviated to PB28.
Series: The Series number indicates the relative price of the colour and is determined mainly by the cost of the pigment. Series 1 is the least expensive, and Series 5 is the most costly. Where there is no series column, this indicates the price is uniform across the range.
T/O - Transparency/Opacity: Transparent colours are marked ‘T' and semi-transparent ‘ST.' Opaque colours are marked ‘O' and semi-opaque ‘SO.' Transparency, however, is relative, and the ratings are provided as a guide only. In addition, any thin film of colour will appear more transparent than a thicker one.
Permanence: The permanence of an artists' colour is defined as ‘its durability when laid with a brush on paper or canvas, graded appropriately and displayed under a glass frame in a dry room freely exposed to ordinary daylight and an ordinary town atmosphere.'
In simpler terms, their resistance to change is when exposed to light and the atmosphere.
Lightfastness: Lightfastness is shown with an ASTM rating for the pigment. The ASTM abbreviation stands for the American Society for Testing and Materials. This organization has set standards for the performance of art materials, including a colour's lightfastness. In this system, I has the highest lightfastness available, and V is the lowest, though ratings I and II are considered permanent for artists' use.
Where no ASTM rating is given for a Winsor & Newton colour, it is labelled as N/L, meaning "Not Listed," this usually indicates that the ASTM has not yet tested the pigment or the type of range. It does not necessarily imply a lack of lightfastness.
In these cases, we recommend that you refer to the Winsor & Newton permanence rating, which evaluates colour on many aspects, including lightfastness, and indicates a colour's ability to resist fading.
