The full name for this pigment is benzimidazone yellow. It has exceptional lightfastness, superior to any of our other organic yellows. The 6 G rating refers to a scale used by pigment manufacturers indicating how close to green a yellow is. 6 G means 6 steps toward green. (Compare with Hansa medium yellow, rated 2G, or hansa light yellow rated 10 G). Benzi Yellow is the yellow that we recommend as a “process” yellow for use in three colour process work. It is close enough to green to make a full range of greens when blended with blue, yet is not so green that it cannot make good oranges when blended with red.
Benzimidazolones are one of the most recent pigment groups to come on the market. Although their performance matches and exceeds many other pigments in this colour range, Benzimidazolone pigments are unfamiliar to the public in the form of a single pigment colour, yet are used by manufacturers of artists paint, where several pigments are blended to create a hue. For example “Naples yellow hue” has been made from benzi yellow modified with earth tones and white.
