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...
