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).
