&gt;&gt; Indeed yellow to red is the range of hues that some human females might be able to discriminate better than males.<p>That&#x27;s interesting indeed, because I was wrong about the male&#x2F;female dichotomy in Indian traditional dress: yellows and reds (and also fuschias, turquoises and so on) are worn equally by males and females. Blues and purples are also very commonly worn by women. The difference is in the patterns and the shape of the dress, but not in the colours. Apologies for that- like I said I&#x27;m Greek, not Indian.<p>Additionally, the other cultures I mention have an equal spread of reds, yellows, and what have you among men and women, so again I don&#x27;t see how any genetic thing is at play here.<p>Finally- All this doesn&#x27;t say anything about why pink is &quot;girly&quot; only in specific parts of the world. If pink in particular was a genetic thing then it would be all over the place, not just in a few countries.
