Here is a mind-blower: blue for boys and pink for girls is a brand new concept, relatively speaking. In my musings about contrived gender concepts, it occurred to me recently that the pink/blue notion has an origin. Someone made that up!
It turns out that the origins are not terribly clear, but there is a lot of amazing information about at least some of the influences. First off, think back to photos you may have seen of babies in the early 20th century. They are usually wearing the standard white gown. Some of those babies are boys. Those gowns were fairly standard through most of the 1940′s, which means that even people as young as the Baby Boomers were not stamped with blue or pink upon birth.
To boot, it seems that the notion used to be that pink was for boys and blue was for girls. The thought was that pink is a shade of red, which is typically thought of as a strong and fiery color suitable (or perhaps desired more than suitable) for males. Blue is typically thought of as a softer color suitable (desired) for females. Saint Mary is most often depicted in light blue, which undoubtedly had influence.
The earliest known examples of pink-clad girls and blue-clad boys are found in the 1940′s, seemingly as a result of marketing strategies by companies to push individualized merchandise. This seems probable to me, as indeed if one has a female child followed by a male, everything would need to be repurchased. Though the question remains: why pink and blue?
There are a number of experiments (sourced below) that have been run to determine whether or not an innate preference exists, but I am dissatisfied with most of the results. One experiment suggests that humans in general may prefer shades of red. Another suggest that there are physical differences in the eyes that may be the result of our hunter/gatherer days. The fact remains that blue/pink as a rule was only very recently created and I think it is worth considering the ways in which it can be damaging. At best, it is just unnecessary.
For further reading, I recommend the work of Jo Paoletti from the University of Maryland.
