I'd pick the cupboard white first. Pick what you love. Then get the wall colour tinted to match the cupboards. Nothing worse than mismatched whites. Either match them or go a contrast on the wall.

Do you happen to know what sort of paint has been used on trims? It can sometimes be a very big job to properly prepare them for repainting so the paint sticks. We have found ours wasn't done right in the past and is coming away. Not looking forward to doing it all correctly. I would much prefer to spend the money on beautiful bright artwork! Changing the door colour as big reader suggested sounds like a good first step before deciding to do it all.

Who says you have to have the same colour inside and out. I have double hung windows that are different colours. Yes, there is a 'seam' where the two colours meet but it's only really noticeable when the windows are wide open and even then only pedants notice.

I feel that it would be pity to paint an antique Would you consider etching a floral or geometric pattern on the mirror? That would add some white to the cupboard without spoiling something with its own character & patina of age It would be easier to replace the mirror than remove the paint at a later date All the pieces you have chosen are lovely & should sit well together Good luck with the birth of your baby
