Scanning through the BBC news pages I find this little snippet:
Pink was a boy's colour while blue was thought better for girls - a "generally accepted rule" according to The Ladies Home Journal in 1918, which described pink as "more decided and stronger" while blue was "more delicate and dainty".
followed later on the same page by:
The colour pink gets its name from the jagged-edged dianthus flower, commonly known as a pink, which in turn got its nickname from pinking shears, those serrated scissors used by seamstresses.
Having just gone through months of telling people that white is not actually a "traditional" wedding colour and that Victorian brides would have just worn their Sunday best dress, usually in a serviceable colour, so no there is nothing wrong in having a black wedding dress, it was nice to see a reference to an accepted colour association being changed just to prove that it wasn't me making things up.
