Gemstones & Pearls:Gemology
Color Communications Tool
Howard Rubin's two-year project culminates in Color Toolbox, linking
several color communication systems
Color communication just got easier, thanks to the development of GemDialogue
Color Toolbox,a book that cross-references the many color communication
languages in use today.
Retailers, gem dealers and manufacturers use a variety of methods to
communicate the color of gemstones. Some use simple descriptive language
such as orangy-red. Others use methods based in color science.
One system is GemDialogue, which uses transparent color-scale charts
that can be combined or used with tonal masks to provide users with 60,000
color possibilities. This works as long as the people communicating use
the same system. GemDialogue's developer, Howard Rubin, acknowledges that
at least seven systems including his are in use, which prompted
him to develop the cross-referencing guide.
His project is not endorsed by any other color communication system,
but it's an important step in helping the user of one system to communicate
with the user of another. Rubin says his two-year study is the result of
visual comparisons he and coauthor Gail Brett Levine made. "We cannot
guarantee that all users will view the results the same way, however, we
feel the approach is thorough enough to fill a void which exists in the
jewelry industry," he says.
