Colour decision
Anthracite grey or agate grey: choosing between the two
Short answer
Anthracite grey (RAL 7016) is a dark, near black grey that gives strong contrast and a modern look. Agate grey (RAL 7038) is a lighter mid grey with a warm undertone that sits more quietly against varied brick. Pick anthracite for a bold outline, agate if you want a modern frame without heavy contrast.
The two colours in plain terms
Both are standard RAL shades, so the same colour can run across your front door, windows and patio doors. Anthracite, RAL 7016, is the default modern choice for composite doors and uPVC casements right now. Against red brick it reads almost black. Agate, RAL 7038, is noticeably paler, a soft mid grey with a hint of warmth, and it is our most fitted alternative to anthracite.

How each looks on local homes
On a red brick Victorian terrace or 1930s semi, anthracite gives a crisp, defined outline to every frame, which suits people who want the windows to be a feature. It also works on new build estates with light render. On the same red brick, agate softens the look: the frames read as grey rather than black and blend a little into the wall.
On pale stone, buff brick or render, anthracite can look heavy, especially across a whole house of windows. Agate is often the better balance there, and on shaded elevations where a dark grey can make a frontage feel gloomy.
Practical differences over time
- Water marks: agate shows water marks and dust less than anthracite.
- Heat: darker frames absorb more sun, so agate gains less heat in summer.
- Contrast: anthracite makes glazing bars and frames stand out; agate keeps them low key.
- Inside: both can be ordered dual colour, with white on the room side.
How to choose
Hold samples of both against your actual wall in daylight, on the elevation that will be seen most, and look from the pavement rather than up close. Think about the roof tiles, gutters and any existing door you are keeping. If the frontage is mid toned or shaded, agate is worth serious thought. If you want a strong modern outline on red brick, anthracite is the safe choice.
