In the Color Management settings in the Spot Color Definition.
Lab values in english
In Portuguese, should be "Cores Lab" and not "Cores de Laboratório"
Google and Bin say that you're wrong, go figure.
These are automatic translators, I am a color specialist, human and made several translations.
I only want to help.
If you prefer automatic translation...
Color Lab is about the color space named Lab, or L*a*b* definied by CIE in 1976.
"Laboratório" is Laboratory is about a place where scientists do reasearch.
I hope I clear enough.
Thank you for your reply.
