Calculate characteristic Color analysis values from UV/Vis spectra on single mouse click. Compare several color analysis results at a glance.
Color analysis is performed within 360 to 830 nm spectral range. Results are displayed in a comprehensive report including meaningful color plots.
Analyze and compare two or more spectra in a single analysis and determine color differences easily.
Last used analysis settings are kept for your convenience. Hence, batch sample analysis becomes a single click application. Save time and money by increasing your analysis efficiency with our color analysis and comparison.
Results of color analysis provide valuable information on e.g. forensic, surface, coating, painting and damage analysis.
Analysis is carried out using spectral data in its original spectral resolution or in either 1, 5, 10 or 20 nm resolutions. Required weighting factors are calculated according to ASTM E2022-16 and E2729-16 from tabulated 1 or 5 nm values. Measured sample spectra will be prepared according to methods described by Stearns et. al. improved by Fairman.
The following standard observers are used according to CIE S 014-1:2006 and ISO 11664-1:2007 respectively:
Various illuminants can be used for color analysis including the CIE standard illuminants and also an enhanced set of further well known illuminants:
Calculation of tristimulus values is the initial step in color analysis according to ASTM E308-18 and CIE 015:2018 respectively. Especially data preparation methods to resolve spectral resolution issues are applied. Tristimulus values are calculated according to CIE S 014-3:2011 and ISO 11664-3:2012 respectively.
Color coordinates are determined for multiple color spaces:
The resulting color parameters are displayed in corresponding plots, and related values are summarized in a comprehensive report. Various standard or custom light sources and the CIE 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.
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 spaces.
Two UV/VIS spectra can be directly compared in this way according to ASTM D2244-16.
