I don't think the monochrome kid's bedrooms or nurseries will be disappearing any time soon. I am the first to say I love it, but being the colour loving junkie that I am, I just can't help myself but adding a pop of colour in there.
Especially in a girl's bedrooms.
Adding a pop of pink in a monochrome theme is perfection in my eye.
It's so clean, unfussy & lovely. If you're not interested in creating a whole bedroom in this theme, why not just add some as decor?
My moon dancer personalised cushion is just that.
Black, white & a pop of pink. What is ideal also is that it will still coordinate really well with current decor that is pink.
