  BabelColor Color Translator & Analyzer (CT&A) for Mac and Windows

  • Version 4.5 (December 2014): Color and Tone monitor uniformity as per ISO 12646:2014-Final Draft; Version 4.2 (July 2014): Color Rendering Index tools: CRI, CQS (NIST Color Quality Scale), CRI2012 (nCRI Version 12), GAI (Gamut Area Index), MCRI (Memory CRI)
    (What's new?)
           <-- CT&A on the Microsoft Surface Pro!

    BabelColor CT&A is a collection of tools specifically designed for Color Translation, measurement, & Analysis. Tools are grouped by theme in individually managed windows; these windows are controlled with a menu or a toolbar window.

    The RGB vs RGB tool is a bidirectional RGB color-space translator and comparator tool. The RGB vs RGB tool accepts manually entered L*a*b* and RGB inputs; it does not require a color measurement instrument although many colorimeters and spectrophotometers can be used to input data (instruments purchased separately; a list of supported instruments is available here).

    All other tools need spectral data in order to provide results; these tools are collectively called spectral tools. The CRI tools can accept input from an i1Pro or i1Pro 2 fitted with am ambient adapter OR from a file (an instrument is NOT required). All other spectral tools require a connected i1Pro or i1Pro 2 spectrophotometer, manufactured by X-Rite (the FluoCheck tools can only use an i1Pro 2).

CT&A tools for whiteness / brightness / fluorescence / opacity

FluoCheck (New in CT&A 4.0): The FluoCheck tools are made possible by the capabilities of X-Rite's i1Pro 2 spectrophotometer which supports the M0, M1, and M2 Measurement Conditions as defined in ISO 13655-2009. These tools were devised by BabelColor to rapidly evaluate if a color sample is susceptible to fluorescence and if two samples that match without fluorescence still match when fluorescence is taken under consideration.

Whiteness tools: These tools are specifically designed to measure white paper Whiteness, Brightness, Fluorescence, and Opacity in three clicks of your i1Pro or two clicks of your i1Pro 2 (the instruments must be non-UV-cut model). Since these measurements need to be done on compliant white and black backings, and require a well characterized UV-cut filter for fluorescence measurements if using an i1Pro, we also provide tools to check the compliance of such backings and measure the characteristics of UV-filters (backings and UV-filter not included).


Display-Check is a specialized tool of PatchTool. Use it to check your display calibration or to certify your monitor using the recommendations of IDEAlliance.

Many popular colorimeters and spectrometers are supported.

Click here for an example of a monitor certification report you can get from PatchTool (converted to a PDF format).

Please download Application Note #4 (AN-4) on the Tutorials page for instructions on on how to get similar data.

Use this tool in association with BabelColor CT&A ISO 3664 tools for complete monitor analysis.
