These 2 articles might provide more guidance. [Choosing Exterior Paint Palette[(https://www.houzz.com.au/magazine/5-easy-tips-for-choosing-your-exterior-paint-palette-stsetivw-vs~3317364) http://www.stylishlivablespaces.com/exterior-colours/tips-for-a-sucessful-exterior-colour-scheme I'd paint samples on large boards rather then areas on the house. That way you can move them around & see how they look on all aspects at different times of the day. Also, try view the colour on its on and not best to one of the others. If you haven't found the ideal colour today, revisit the store and look at they're entire catalogue, not just paint chips they have on display. Good luck!

Bi Je, they are dark green at the moment but will be changing once i reach to the point of painting the house

I like the darker charcoal and white , if repainting make sure it is a nice deep charcoal , NOT a dark grey -- as gwyn says , why be ordinary ? I'll offer 2 thoughts though -- the first would be a bit more white , such as the terrace railtop , and maybe a small 'sculpture panel' on the main wall ( it looks like there is one on the end wall ? ) . Easy to do . Option 2 and 2a is not quite so easy , and may not suit the neighbourhood , but 2 more authentic colour options -- Scandinavian Red is what I would call Barn Red -- with the white highlights that looks the part ! The other option on that thought track is Swedish Blue -- authentic , but not a favourite of mine , and again it may look out of place amongst the neighbours , and its too close to grey for my liking , but with crisp white highlights it can look okay . So I suppose 3 options from me haha -- slightly darker charcoal , with white highlights ; Scandinavian red with white highlights ; Swedish Blue with white highlights .

Makes more sense to me now . And great to see a roof that isn't grey ! In the first pic you posted , I would have gone for the lighter grey , but seeing that whole picture , and the roof and garage door , I actually like the darker monument , MAYBE doing the garage door in woodland ( I see you want to change that , so you'd have to envisage how that would look too -- for example , 3 or 4 windows will lighten the look , so by going for the lighter woodland will highlight that , and the monument elsewhere would contrast that ! Oh , and hopefully you will paint or change the letterbox -- that purple tone doesn't do anyone any favours ! It would look smart in either of the greys , albeit a bit dated .
