Color Correction Matrix.
- Version 1.0 (March 2012): First Release!
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
Google play Web site (previously called the Android Market).

BabelColor CT&A tools for: whiteness / brightness /
fluorescence / opacity
(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
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).
Correction Matrix tool
Use this tool to determine a
Correction Matrix between two instruments according to
E1455-2010. A Color Correction Matrix helps improve inter-instrument
agreement in emission (i.e. display) measurements; it can also be used
to correct the response of a colorimeter designed for standard LCD
displays when doing measurements on a wide gamut display. Please read

Matrix tool, with an example on how inter-instrument measurements are

Uniform Color Scales
The document contains examples of how to navigate within this color
space and presents many color scales (color ramps) images which can be
generated with PatchTool. The document includes four mini-tutorials. In
particular, one tutorial shows how to generate a uniform list of colors
which completely fills the gamut of a device profile; such a list can
then be used to check a monitor's accuracy with PatchTool
for instance. Another tutorial shows how to compare the gamut of two
devices in specific color ranges. This document can be downloaded in the
