"The Shadowtone ornamental technique was developed by the head of Onondaga's decorating department, Harry Aitken, and was introduced in 1938; the pottery produced nearly three hundred patterns in this line using a sophisticated decorative process that employed stencils and air-brushed glazes."

Although the pattern was used by the Neptune Room Restaurant until 1963, it is likely it was considered a stock pattern after their closure and available to other venues. Custom pieces have been found topmarked with Robert's Fish Grotto – Sacramento in a slightly paler color scheme.
