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
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).

is a tool designed to compute color-differences using industry standard
formulas. Compute DeltaE* (DE*)
with the CIELAB, CIE94, CIE94-textile, CMC(1:1), CMC(2:1), and CIEDE2000
formulas. This program is designed specifically for the
Android OS and can be purchased from the

CT&A tools for whiteness / brightness /
fluorescence / opacity
FluoCheck: 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. 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
Many popular colorimeters and spectrometers are
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.

for complete monitor analysis.
