EquiColorRTM is a system that captures transmitted or reflected light with one or two probes augmented with light sources, determines the spectral transmission or reflection curves, deduces the human-perceivable color associated with such spectra, and is able to check its deviation from a configurable expected color.

ReTA helps to gather a growing bunch of log files with RTM data, extract concentration data from the spectrometric data, discover the RTM segments and their textual descriptions, align the beginnings, synchronize the proceedings, filter out noise, combine selected subsets for averaging, estimate asymptotic behavior, convert the resulting curve into a viable approximation of a probability distribution, display the result, and derive further statistics from that, including estimates of percentile times.

SpecViewer is a tool designed to display and navigate the sequences of spectra in an intuitive way, presenting both overview and details graphically and assisting analysis by offering common transformations that emphasize relations between spectra. The human-visible color associated with each spectrum is directly visualized by presenting the spectral curve itself in that color.

EquiColorRTM can condense the measured spectra to coordinate triples relevant to human vision, typically L*/a*/b*. Each such triple can be thought of as representing a point in a 3D color space. Given a sequence of such measurements, one obtains a point cloud in that color space. Suppose that another point cloud has been obtained in an earlier sequence of measurements. It would be interesting to quantify how close the two point clouds are in a statistical sense. This is the function of CloudVis.
