Hi Karsten.
In 16-bit Lab the results are even *more* imprecise, if that makes any
sense!
If I manually enter L* 73, a* -28, b* -25 into the Color Picker in 8 bits,
after I fill the document and run the script I get {class:Lab color,
value_L:72.94, value_a:-28.0, value_b:-75.0}.
But if I enter those same value in 16-bit mode, the values that the script
retrieves are {class:Lab color, value_L:72.94, value_a:-27.61,
value_b:-74.79}: *less* precision! What's the meaning of that?
Regards.
