Color tool provides calculation for color space transformation and color comparison (deltaE)and displays spectral data.

- Creates and loads custom CIE Lab colors.
- Spectral data graph and the XYZ tristimulus from ISO 13655:2009.
- Reads files containing spectral data from 380 to 730nm at 10nm interval.
- Edits the custom LAB color file with your favorite text editor.
- Works in external storage.
- Imports files provided by : FOGRA/ECI2002/BasICColor/i1Profiler/ColorPort/CgsOris suite/Japan Color/IdeAlliance/Swop...
