'1. It says so on Wikipedia.
Wikipedia says, “We do not expect you to trust us.” It adds that it is “not a primary source” and that “because some articles may contain errors,” you should “not use Wikipedia to make critical decisions.”
Furthermore, as Wikipedia notes in its “About” section, “Users should be aware that not all articles are of encyclopedic quality from the start: they may contain false or debatable information.” ' - http://www.findingdulcinea.com/news/education/2010/march/The-Top-10-Reasons-Students-Cannot-Cite-or-Rely-on-Wikipedia.html
"Etymology and definitions
The color pink is named after the flowers called pinks, flowering plants in the genus Dianthus. The name derives from the frilled edge of the flowers—the verb "to pink" dates from the 14th century and means "to decorate with a perforated or punched pattern" (possibly from German pinken, "to peck"). While the word "pink" was first used as a noun to refer to a color in the 17th century, the verb "pink" continues to be reflected today in the name of those hand-held scissors that cut a zig-zagged line referred to as pinking shears." - https://en.wikipedia.org/wiki/Pink
