Welcome to Spec-Tru - a Standard Color Reference for Transparent Glass that offers a True Spectrum of Colors.
Spec-Tru is a portable and inexpensive color reference system that combines the functions of colorimeter and spectrograph in a small hand-held package.
It is a great tool for cataloging the colors in one's own glass collection, or for describing colors of insulators, bottles, jars, and other colored glass in letters, e-mail, trade lists, and over the telephone.
Please visit all our pages to learn more about identifying the many colors of transparent glass. They are best viewed with Microsoft Internet Explorer v6 or Netscape v7.
