a photo would help to see the walls, floor colour etc. Also how old is your child re length of curtains?

What cute bedding! Depends on your wall colour. If the walls are quite neutral then I think the duck egg within the bedding is a lovely shade. However if you want the curtains to last and adapt with the changing bedding as your child grows, then perhaps simple white would be good, or a shade near to the wall colour if it’s a calm shade. Here are some examples of pale or white curtains.

Hi Charlotte, what fun bedding! I would choose a colour or two from the bedding and use those in other accessories and the curtains across the room. For me I think I'd choose the blue and teal - they will last as a colour palette into teenage hood and also are very versatile. they are also fun and playful and you don't want to overlook fun in a child's room. Do post the room when it's done!

Hi Charlotte, as the bedding has a few colours you have quite a bit of choice. If you get the curtains professionally made they would last you for many years and you can choose a fabric and colour way that would work now and when your children are older. Let me know if you would like any help with this.
