Color Analysis & Comparison

Color analysis and color comparison according to CIE 1976 and DIN/ISO (DIN 5033, DIN 6164 and DIN 6167) standard methods are the focus of our very special Color add-on module.

Multiple color models are applicable for color determination:

  • CIE 1976 Color Model
  • L*a*b* Color Model
  • L*u*v* Color Model
  • Hunter L*a*b* Color Model

The resulting color parameters are displayed in corresponding color diagrams, and related values are summarized in a comprehensive report. Various standard or custom light sources and the standard observers (2° and 10°) can be adjusted to match required analytical conditions.

Colorimetric results can be easily stored, printed as a report, or transferred into other applications such as Word or Excel.

Color Analysis

Valuable parameters, e.g. for forensic approaches, are derived from UV/Vis spectra, covering the visible spectral range from 380 nm to 780 nm of a spectrum for the desired color models. Our color analysis provides you with the following results:

  • Tristimulus Values
  • Chromaticity Values
  • Hue Angle
  • Dominant or Complementary Wavelength
  • Whiteness
  • Tinting Index
  • Gardner Index
  • Whiteness-Blue Reflection
  • Yellowness Index
  • Excitation and Complementary Purity

One or more spectra can be analyzed at once for a direct and visible comparison of the results and differences.

Color Comparison

In many cases, analysts need to quantify the differences between two colors. After determination of required characteristic color values, the software will provide a detailed report showing the color differences under consideration of all available color models.
Two UV/VIS spectra can be directly compared in this way.
