What colour door goes with anthracite grey windows?
Anthracite grey (RAL 7016) is the most requested non-white frame colour in the UK, and it is a cool, dark, near-black neutral. Three approaches work with it, and one does not.
Match it. Anthracite door with anthracite windows gives a unified, contemporary facade. Frames, door, guttering and fascias in one tone read as a deliberate scheme rather than a set of separate decisions. This is the safest choice and the most common.
Go darker. A black door against anthracite frames gives depth without introducing a second colour family. It works because both are cool neutrals.
Contrast deliberately and boldly. Dark green, deep navy, or an oak and timber tone all hold their own against anthracite. Timber finishes work particularly well, because the warmth answers the coolness of the grey instead of competing with it.
What fails: a mid-grey or light grey door beside anthracite windows. Close but not matching reads as a mismatch rather than a choice, and the eye finds it immediately.
Two of these are easy for us to supply, because light grey (RAL 7035) and anthracite grey (RAL 7016) are both standard colours in our range, and interior and exterior colours are specified separately. Our grey windows and doors page shows both shades against different facade types.
