Correct. Labelo's right on. It is in reference to the warmer colors we cut in AVR and also AVC.
Adjectives that have been used are ...
Creamy, antique lace, warm, sunny, lemony (for the darker colors), vanilla cream, etc. all of which embody the essence of the older cuts too as many of them were in fact of the warmer body colors.
When we first began cutting these we had no intent on cutting colors lower than J but after many requests and consumer demand we have and do stock both a white and warm inventory of AVR & AVC.
All the best,
