Rit maintains dye color charts on its website at RitStudio.com. There are three sets of charts: core colors, Pantone seasonal colors and archive colors. Rit does not sell archive and Pantone colors as pre-mixed dyes and instead provides them as a reference tool.
The Pantone seasonal color chart does not represent dyes that Rit sells as of 2015. Instead, it is a mixing chart for Pantone's seasonal color releases. However, customers can achieve these colors by mixing Rit's core color dyes in the proportions listed.
Rit's archive color chart also contains mixing instructions for core color dyes. Customers can follow the provided mixing instructions to recreate Rit's discontinued dye colors.
