Composition and Permanence
The color index name is established and published by the American Association of Textile Chemists and Colorists and The Society of Dyers and Colourists. The color index name is a generic category and does not refer to a specific pigment. While it enables the artist to form a general idea of opacity, transparency and lightfastness, for a pigment in a certain color space, it does not provide definitive information. Many grades of pigment are available from a number of manufactures with a very wide range of physical attributes.
The chemical name is a brief, commonly used generic type designation of the pigment types composition. in conjunction with the color index name, the chemical name can be used to broaden the artists understanding of the source and nature of the pigment used.
The permanence of a color is a measure of the lightfastness of the pigment when dispersed in a vehicle and subjected to conditions which emulate the exposure normally given a fine arts object. Such ratings are generally considered vehicle or media dependent and can vary between media — thus pigment which is suitably lightfast for oil color, might not be lightfast in watercolor. Our ratings utilize a combination of historical data, accelerated testing and data from pigment manufacturers to establish one of the toughest standards among artists color makers today.
Transparency and Opacity
Each of our colors has been provided a designation indicating relative degrees of transparency to opacity. Please consider these as a guideline because any thin film application, while not necessarily transparent, can be interpreted by the view as such.
As an essential ingredient in our binding medium, honey contributes to moistness for smooth, easily controlled applications, increased pigment concentrations, and freedom from over reliance on preservatives. Because of the honey medium, our watercolor resists hardening on the palette, or in the tube. It dilutes easily, often after months of disuse.
We spend hours milling our colors to coax the highest pigment loads into our paints. Compare us. We believe you will agree, M. Graham makes better color. Learn More »
