ELI5: Why do (most) toys targeted at young girls incorporate pink and purple in their design, whereas boys seem to have a much larger choice of colors to choose from when it comes to toys?

Whenever I got to the shopping mall, if I walk past the 'girls' aisle my eyes will see nothing but pink. I understand that western culture has assigned the different genders various colors, but they could at least get some variety in.

Marketing reinforcement - companies, especially established toy companies, are unwilling to try something new.  

You teach girls from a young age to like pink and purple but not like "boy colours". Then suddenly you start releasing things in "boy colours" - uh oh, now the girls don't want it! You'd need to switch your advertising to target parents instead, because even if *you* change your colours, all your competitors haven't, so those young girls are still getting convinced that they need to buy pink.
