ColoSol executable software to perform colour space model transformations for soil colour
The software
What the software does: (i.) Transforms RGB data to dRGB, XYZ, xyY, CIELUV, CIELAB, CIELCH, Helmholtz coordinates, Munsell HVC and a Redness index, (ii.) Transforms Munsell HVC data to XYZ, xyY, CIELUV, CIELAB, CIELCH, Helmholtz coordinates, RGB, dRGB and a Redness index.
Once you press 'Run', you may either (a.) enter values manually using numeric controls and slide-bars or (b.) input a tab delimited (ASCII) '.txt' file for multiple conversions. In this case you can also save all the transformations into a '.txt' file.
This is what ColoSol looks like:

This software is fully operational, however, I will appreciate your thoughts and suggestions for further improvement. If you would like to acquire a copy of it, please email me and I shall let you know how to download it.
