I love bright colours. I stopped choosing my DD's clothes when she was 3yo as she has her own opinions. She loves dresses and all things pink and my little pony. I am happy for her to wear what she wants. They're just clothes.
And to the 'pink' lego haters who go on about lego friends being the devil's work. Look up scala or belville. Pink lego has been around for a long time. And before friends the choice was castle, pirates, police, fire, dinosaurs, space, monsters, atlantis, trains, chima, ninjago, more bloody police and fire, construction sites, coast guards, bionicle as well as the endless star wars. All with very few female minifigs. Gender neutral? Really?
All I see when I look at vintage primary colour lego is how bloody boring it is. Lego is a business. It's goal is to make money. My DD loves lego friends and disney princesses. They are toys.
If a child grows up with healthy role models and are encouraged to have their own opinions and be themselves then the toys they play with, and clothes they wear as toddlers don't matter at all.
I spent many happy hours as a child in the early 80's surrounded by pink plastic. Barbies, MLP's, dolls and prams, a cute wendy house with an iron and ironing board. Made no difference to my adult life choices at all.
