Description
Rublev Colours Bone Black is made from charred animal bone and horn but not from ivory. It is a neutral opaque black that has high tinting strength and is highly staining. The term ivory black is currently applied to a high-grade bone black by other watercolor manufacturers, which is the same grade of bone black we use to makeRublev Colours Bone Black, but we specially make it for watercolors.

Note: Colors swatches are shown in mass tone, at top, mixed with an equal amount of water and brushed out toward the bottom. All pictures of color swatches in this web site are only approximations of the actual color of the watercolor paint. We have taken every care to match the color in these pictures on calibrated color monitors to the actual color. However, because of the wide variance in color monitors the results you get may vary.
