Okay a techie DIY show specifically for girls;

That's so great, but does it really have to be so PINK?

Did you know that it used to be the other way round; Blue for girls and Pink for boys?

"At one point pink was considered more of a boy's color, (as a
watered-down red, which is a fierce color) and blue was more for
girls. The associate of pink with bold, dramatic red clearly affected
its use for boys. An American newspaper in 1914 advised mothers, "If
you like the color note on the little one's garments, use pink for the
boy and blue for the girl, if you are a follower of convention." [The
Sunday Sentinal, March 29, 1914.]

"There has been a great diversity of opinion on the subject, but the
generally accepted rule is pink for the boy and blue for the girl. The
reason is that pink being a more decided and stronger color is more
suitable for the boy, while blue, which is more delicate and dainty,
is prettier for the girl." [Ladies Home Journal, June, 1918]

According to Jo B. Paoletti and Carol Kregloh, "The Children's
Department," in Claudia Brush Kidwell and Valerie Steele, ed., Men and
Women: Dressing the Part, (Smithsonian Institution Press, 1989). -
In the United States: "The current pink for girls and blue for boys
wasn't uniform until the 1950's.

It would also seem that Nazi Germany had something to do with the
association of pink with femininity:

"Catholic traditions in Germany and neighboring countries reverse the
current color coding, because of the strong association of blue with
the Virgin Mary...the NAZIs in their concentration camps use a pink
triangle to identify homosexuals. (The yellow star of David is the
best known symbol, used of course to identify Jews. The German system
was quite complicated, using various symbols an colors to identify
criminals, political prisinors, an a whole range of other groups). The
NAZI's choice of pink suggests that it by the 1930s was a color that
in Germany had become associate with girls." - "Gender Specific

Here is another site backing the same color history.

"The preferred color to dress young boys in was pink! Blue was
reserved for girls as it was considered the paler, more dainty of the
two colors, and pink was thought to be the stronger (akin to red). It
was not until WWII that the colors were reversed and pink was used for
girls and blue for boys..." - Quote from Dress Maker Magazine

"Jo B. Paoletti concludes that the effect of color-coded gender
differences (pink for girls, blue for boys) existed oppositely
initially..." - Quote from book review "The Material Culture of
