In the exterior of a house, apart from the walls, roof is the second most visible part. The color of the roof, therefore, plays an important role in deciding the colors for other exterior elements of the house like windows, doors etc.
When the walls and roof are in different color then the exterior of a house looks more minimalist and elegant when the color of the window frame is same as the color of the roof.
Moreover, as the color of window trim is concerned, it need not to match with the color of the roof instead the exterior window trims looks best when they are in exact same color as the color of roof fascia.
Some other things that the exterior window frame can match with
DOOR
When the exterior wall color and the window frame color are not same yet complements each other then having the door also in same color door as the window frame can help to continue to contrast throughout the exterior of house.
For this color theme to look good the wall color must be of a different color to the color of window frame. Eventhough the colors can be of same shade but when the color of door and wall are in close proximity to each other to contrast must be visible.
FLOOR
In homes with nice and spacious porch area the color of window frame can definitely match with the color of floor which is mostly in brown shade. This is good technique to try when there are too many color present in the exterior of the house.
Same color floor and window frame keeps the number of colors on the exterior less and helps avoid too sharp of a contrast.
POSTS
All the windows near the entryway can be colored to match the color of front posts at the porch. Sometimes the color of floor may not be such that it can match with the color of exterior wall when used for window frame.
In such a case the color of posts can be used as a reference color to select the color for window frame. Generally most people prefer to have the posts and window frame, roof fascia all in exact same color.
Should the exterior window hinges/trims be also of same color as the color of the roof?
Yes for a clean looking exterior keep the color of window trim and window hinges exactly same.
The color of window hinges and the color of trim at the exterior windows should be something that can blend it with the color of window frame. This will keep to coordinate the exterior wall color with the color of window frame.
When wall and window the exterior coordinate with each other then it becomes much easier for the roof to blend in the exterior of house even if it has a color of slightly different shade.
As per the designers, the key for an attractive exterior is to always follow a continuous contrast throughout the house. This means if two colors on the exterior are looking good then the new color to add should not distrub the contrast of already coordinating colors.
Should the material of exterior window frame and roof be same?
Absolutely not.
If the roof of house is wooden, then the window frame can definitely of material other than wood like aluminium.
Also it is important to be at a proper distance from the house in order to see both the roof and window together. At a distance what’s more visible is the color of window and roof. Thus instead of material, the colors should be in matched properly.
Once painted it is quite hard to tell exactly what material is used for the window frame.
The purpose of roof and window are very different. Thus while selecting material for both these partsm their functioning should be considered. Like windows should be of a light weight material for easy opening while the roof should have a sturdy and water proof layer on top like tiles.
Should exterior and interior window hardware match?
Hinges are the only part of window hardware that are visible from both outside and inside. Instead of painting the window hinge in two different colors it would be best to leave the hinge without any color.
It is only when the color of window frame is same both from outside and inside that the color of window hinges be same as the window frame.
