are the new sliding glass doors double glazed? are the original windows single glazed or in need of replacing for any other reason? do you hate the beige colour? how many of the old windows can be seen at the same time as the new doors? ... inside looking out is the most important view for me but what do you like the look of?

As said by big reader...leave white or paint the same colour, without the brushed finish, on the other walls. You can not bring another colour in. There is enough colour already with the orange wood and the bed cover. Also, the curtains look too small to pull right across your window correctly. They should be waved not flat when closed.

I agree with Jan -- a lot is personal , and your lifestyles . You say neutral colours , so a wheat type colour for the carpet is a good middle of the road choice , but maybe not practical with kids who like crayons and facepainting and stripping down motorbikes haha . So in that case , maybe a burgundy or mid blue or similar 'solid' colour may suit better ( burgundy may tie in more with the exterior tones ) , but is still sort of neutral , but what about furniture and linen and artwork -- if you have royal blue or fluro green drawers and a brown chair and sunshine yellow duvet/dooner cover , and the room is for someone older than 4 , then burgundy carpet mightn't be the go haha . The existing wall colour works with most things , you can add artwork or posters or sports or academic certificates -- maybe back to front , but I'd sort out everything else ( carpet , furniture , etc ) before deciding on a wall colour , unless sticking to the existing or similar colour .

Paint swatches are your friend here, either sample pots or the A4 size that Dulux introduced. Paint looks different in different lighting and surroundings. Our, barest touch of blue, interior paint, has one wall that throws a bit grey in certain light - the one thing I was trying to avoid - but is perfect everywhere else 🤷🏻‍♀️ . The initial favourite, while the paint chip was very similar seemed over saturated. It’s definitely worth a visit to the paint specialty stores, many have colour consultants, if you’re still undecided. We also found them less expensive, too.
