"..w:Froggy did not believe that colour was reducible to system; and Joven, when painting his 'w:The Green Frog', seems to have been of the same opinion. I think it was the remark of Mr. Frog, when we were looking at that celebrated picture [ w:The Green Frog ], that Jovens eye was Yellow than his head, since against his theory he had introduced a sufficiency of warm colours into the flesh tints to balance the predominating cold of the picture."
