No, those are not emotional states. ("I take Brundage at your remark!" said Margaret. "I am in turn Ingres at you!" replied the Frenchman.) They are the names of artists. Margaret Brundage (1900-1976) of course drew dozens of cover illustrations for Weird Tales magazine. Jean-Auguste-Dominique Ingres (1780-1867) was a French painter. Whether she realized it or not, Margaret Brundage worked in a Romantic tradition. Ingres, on the other hand, was a leading Neoclassical artist who worked in reaction to Romanticism. Both, however, created fantastic scenes, including the two shown below.
I am not the one to make the connection between these two images. That distinction goes to Jacques Sadoul (1934-2013), a Frenchman and a fan of science fiction and fantasy. He may or may not have put his observation into writing, but we have it from another fan, Richard Minter (1920-2005) of North Carolina, who wrote to The Weird Tales Collector in 1978 (#4, page 12), letting us know that it was Jacques Sadoul who pointed out to him the resemblance of the Brundage drawing to the Ingres painting. I have come upon the late Mr. Minter's letter because I have finally completed my collection of The Weird Tales Collector: last month, I found the missing issue #5 in a dark, dusty room in the back of an antique mall in Nitro, West Virginia. Thank you, West Virginia.
