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.

consider very dark walls like navy, dark grey, rich caramel or deep rust colours with eaves and fascias white, downpipes same as walls and gutters a mid range colour to match the dark walls (btw some new paints are supposed to have heat reflecting qualities even in the darker colours)

Hi Suzy, the answer could be both yes it could be and no it may not be. The issue here is you're dealing with two existing "whites" in that you have existing rooms painted in the USA antique and the kitchen which you describe as a vivid white. It depends upon many things. What I can say is that colour is perceived relative to immediate context, elements and light conditions. The same paint colour can vary dramatically from room to room, from wall to wall. Check out this link from Resene that demonstrates how colour works with adjacent colours and our eyes are "tricked"one way or the other http://www.resene.com.au/samecolour.htm . This can be used to our advantage but we need to understand and be aware of what's going on. Sometimes it makes sense to follow suit with existing colour, but sometimes a subtle adjustment of tint is required to balance better against a certain element that may be a more dominant aspect in the specific space. This is ultimately getting into the nitty gritty of interior design and the balancing all elements. The beauty about paint is that you can fine tune it to perfection and you can blend/adjust across spaces. What you need to to work it is what option is the option that is the LEAST noticeable. The question is here if you go Antique White, will it throw too much yellow if it's juxtaposed with the vivid white of the kitchen? And if so is there opportunity to change the colour somewhere without making it obvious. Are you using different colours for the trim for example? Could you make a statement/change feature for the kitchen/living space and do something completely different such as a soft grey wall that will set off the kitchen but the grey will work well with both the antique white and the vivid white of the kitchen? Start with a sample of the antique white and put it up against the kitchen and see how it sits. If it looks OK run with that, if it's obvious/looks yellowish, then you may need to consider an alternative strategy. If all else fails it may pay to seek some professional colour consultation. Hope this helps. Cheers PD :)
