Permanent in most media, it performed best in watercolour paints. Bismuth White Developed in the early 19th century it was replaced by Zinc White by the 1830s. The closest modern pigment to Bole would be light red in colour. Bone White Obsolete; it was made by burning bones to a white ash.

It had the advantage of being much less toxic than many other colours, but it was prone to darkening when combined with pigments containing sulfur. Cennino Cennini in his Il Libro dell'Arte says 'the best bones are from the second joints and wings of fowls and capons; the older they are, the better; put them into the fire just as you find them under the table.' It was used as a ground for panels.

Used until the early 20th century, mainly because of its attractive hue.

Burnt Carmine A fugitive dark red type of Carmine but less permanent. Cadmium Pigments A family of pigments based on the metal cadmium, in hues of yellow, orange and red.

Bistre An unreliable brown pigment made by burning Beech wood. Bremen Blue A synthetic copper blue pigment without the permanency of Azurite.

It was manufactured in numerous shades and had many common names.After roasting it was typically mixed with Van Dyke Brown to obtain the richest shades. Burnt Sienna An iron oxide pigment, coloured a warm mid-brown. Cadmium yellow is cadmium sulfide, to which increasing amounts of selenium may be added to extend the colour-range.Viridian is added to Cadmium yellow to produce the bright, pale green pigment cadmium green.It was first synthesized in 1868 by the German chemists, Grabe and Lieberman, as a more lightfast substitute to Rose Madder.Madder lakes, which were produced in a variety of shades of red, from brownish to purplish to bluish, made good glazing colours that spread well in oil, and were also prepared in a form for use in watercolour painting.Given the workaholic nature of many Old Masters and modern-era painters, one wonders how many of them were adversely affected by constant contact with such unhealthy chemical colourants.
