All the suggestions above are perfectly good. However, when you have a house that is entirely painted, the options are so endless that it's easy to get stuck. I'd advise either finding photos of comparable homes in colors that you really love, and reproducing a similar palette on your home… or upload a picture of your house to a colorizing site, and play around with various combos. Sherwin Williams has a Color Visualizer that is decent. I don't mind a white house, but feel that the black trim is a bit harsh. On the railing especially- it feels like it is outlining itself too much. Reduce the contrast between the body and the rail and it will enhance the house rather than overwhelm it. You have a lot of choices, so just experiment and go with what resonates with you.

Do you have any photos of the front of the house that may give us a better view of the green trim? Have to say that painting costs so much and lasts just so long, you may want to wait until it's needed.

Let her help you or you will be changing it again

An old post , so sort of sorry to revive it ! The lighter shade looks a lot better , but something doesn't gel with me -- it looks like a beautiful Million Dollar house , let down by someone trying to save $10k . IF it was my place , the 2 things I would do is change ( or hide ) the round pillars , and the relatively cheap looking brickwork . I'd go for quality stonework in place of the brickwork , and carry the theme through to the pillars -- probably 'squaring' the pillars . In fact , I personally don't like the slightly strange 'extra' pillars -- I'd try to 'cut back' to 4 pillars , in a quality natural stone . Once I had done those 2 'improvements' , I'd sand back and restain a darker brown the entrance doors and surrounds -- that golden look screams 1980's IMO . I realise they tie in with the existing colours , but I'd want to get away from that look . Maybe I'm strange . . . . . . .
