Paint colour and Curtain help please!

[ArtyFartyQueen]

Can anyone help? The husband and I have splashed out on a new bed which is arriving next week and I’d like to paint our walls before it arrives. Does anyone have any suggestions for paint colours plus curtains that would suit a dark grey bed and white furniture please? I’ve attached a photo of the bed!

Navy feature wall behind bed, other walls neutral, white ceiling & woodwork then pick accent colour with navy/neutral for bedding & curtains? DS is having a very similar bed when we move & that's what I have in mind for his loft bedroom except will have velox blinds instead of curtains.
