Same pattern, different colorways

In the second half of the 19th century, as printing techniques improved with roller printing becoming increasingly automated, French textile manufacturers began to occasionally print a popular pattern or motif in more than one colorway. Over the years of buying French textiles, I have seen very few examples of this, so I believe it was not a common practice.
Below are several swatches from the second half of the 19th century. The first two are designed by Georges Zipélius and printed in Alsace. All are high-quality prints from finely-engraved rollers and would have been costly textiles when new.
