The entrenchment of gendered colours has, IMO, become much worse since I had my children 30 years ago. I rarely dressed my DC, both girls, in pink. There were so many colours to choose from in Woolworths, Adams, C&A and the new kid on the block H&M, that pink was a rare purchase.
I've recently become a granny, and I'm so disappointed in the choices available for babies and little children. I went into a large, out of town, Next to buy some baby clothes and was met with a wall of blue and pink. The same for other places too. H&M are still pretty good.
It's all so boring and predictable. Fortunately my DD doesn't buy into gender stereotypes and dresses her little one in lots of different colours, but usually blue!
