Input

1)
CIE L*a*b* , observer 2°, illuminant D65, as per DIN EN ISO 11664-4
CIE L*a*b* is a device-independent color space consisting of 3 color values:
• L* lightness axis
Specified operational range: 0 to 100
• a* green-red axis
Specified operational range: –150 to 100
• b* yellow-blue axis
Specified operational range: –100 to 150
Application
