These shirts are a later version of embroidered linen shirts originating in the second quarter of the 16thC. (more to follow)
Blackwork is still used on collars in some regions. At least one blackworked(silk) linen shirt is known to have been made in the 17thC according to probates 200 years later. It was kept as a family heirloom and mainly used for weddings and special occasions. The blackwork patterns are known from 16thC samplers or pattern books. There might be a few alterations over time. The blackwork is mostly done using weaveseam. Black linen thread or black cotton thread replaces black silk.
Swirly ,flowing patterns comes into vogue after the 17thC. 
The most common embroidery threads would have been wool up to the introduction of cotton thread. This does not preclude silk thread.
Most shirts with blue monochrome embroidery are dated from 1800 and later.
Burgundy and grey is a fairly new addition to the color palette. Probably 20thC.
For a comparisson; look at 16th and 17th C german and english samplers for colors and patterns in vogue at the time. There is one known whitework sampler in Bergen from the 17thC .
