The Sigma-Aldrich Color Chart provides simple, fast, and uncomplicated colour determination of solid chemicals.
The Sigma-Aldrich Color Chart is based on the Munsell? color system and was developed for internal use in quality control of all the Sigma-Aldrich production sites. It contains 51 color chips on a white background on page one. This facilitates and speeds up the daily use of the chart, making the turning of pages unnecessary. Below the color chips are the short codes and the internally defined color names. The other page has a table with hue, value, and chroma for each of the colors according to the Munsell? system.
