&gt; If I&#x27;m buying my young niece a toy, and see two otherwise equal toys except one is blue and one is pink, is it sexist to choose the pink one? I have to make a choice, there is no non-colored toy.<p>This is where knowing how these associations came into being could also help you and also help educate others (including your young niece). Several decades ago, the colors promoted were blue for girls and pink for boys. Today people would be surprised to know this, but what&#x27;s important is realizing that this was all created by a group of people saying &quot;this color is what is appropriate for this gender because...(prejudices)&quot;, which basically sounds ridiculous.<p>Here&#x27;s an excerpt from an article [0] on Jezebel (I found it by searching for &quot;girls blue boys pink&quot;):<p>&gt; From Smithsonian.com:<p>&gt; Ladies&#x27; Home Journal article in June 1918 said, &quot;The generally accepted rule is pink for the boys, and blue for the girls. 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.&quot; Other sources said blue was flattering for blonds, pink for brunettes; or blue was for blue-eyed babies, pink for brown-eyed babies, according to Paoletti.<p>&gt; In 1927, Time magazine printed a chart showing sex-appropriate colors for girls and boys according to leading U.S. stores. In Boston, Filene&#x27;s told parents to dress boys in pink. So did Best &amp; Co. in New York City, Halle&#x27;s in Cleveland and Marshall Field in Chicago.<p>----------<p>Here&#x27;s an excerpt from a similar article [1] from BBC that explains that there are no gender specific differences in babies&#x2F;kids and that in adults blue is the most preferred by men and women:<p>&gt; Various studies have looked at colour preferences in different age groups. In the US most have found that babies and toddlers, whether male or female, are attracted to primary colours such as red and blue. Pink doesn’t feature high on the list, although it is more popular than brown and grey.  Some studies of this age group have found blue is favoured, others red, but they rarely find any gender difference.<p>&gt; In 2007, research conducted at Newcastle University in the UK asked adults for their favourite colour. Did most of the women choose pink, or even red? No. The colour which came out top, for both men and women, was blue.<p>[0]: <a href="http:&#x2F;&#x2F;jezebel.com&#x2F;5790638&#x2F;the-history-of-pink-for-girls-blue-for-boys" rel="nofollow">http:&#x2F;&#x2F;jezebel.com&#x2F;5790638&#x2F;the-history-of-pink-for-girls-blu...</a><p>[1]: <a href="http:&#x2F;&#x2F;www.bbc.com&#x2F;future&#x2F;story&#x2F;20141117-the-pink-vs-blue-gender-myth" rel="nofollow">http:&#x2F;&#x2F;www.bbc.com&#x2F;future&#x2F;story&#x2F;20141117-the-pink-vs-blue-ge...</a>
