I am very pleased with the coloration of the blue Flores and the ombre. My friend who created the 'file' did the ombre and then placed the Flores on top. So...I was also able to print just the ombre. The blue is the document color. That said...my book ( Laines 1849) contains 100s of antique fabric samples, many of which are a version of Prussian Blue. They differ slightly....probably a function of the formulation of the dyestuffs as well as differences in the printing/finishing processes used by assorted Mulhouse printers mid 19th Century.
Samples available at no charge.
