Hi,
Same thing for greens: up from 0/135/0 to 0/255/0 the a* is -128. Values of 136G an above are imaginary colors.
sorry, this isn't true. 128 is an arbitrary limit imposed by particular computer encoding (i.e. 8 bit L*a*b* encoding). There are perfectly real (i.e. within the spectrum locus) colors with a* or b* values outside the -128 to 128 range.
Yes i know, and I verified that already by eye for real life yellows above b=128. But do you really think, that there are almost as much greens beyond -128 a* than within? MfG Thomas
