Black is RAL 9005 — jet black — and it is the colour that gives you the Crittall look. It has the strongest contrast of any window finish, which makes it superb on white render and pale brick and risky on dark red brick.
Black windows are spectacular against white render, light grey render, buff brick, painted brick and stone. The frame reads as a deliberate graphic line and the whole elevation sharpens up.
Against dark red or brown brick, black windows can read as voids — the openings vanish into shadow and the elevation loses its rhythm. On that stock, anthracite grey (RAL 7016) almost always looks better. It is worth holding a sample against your actual wall in daylight before committing; the difference is not subtle.
Gloss black shows every rain streak, every fingerprint and every ripple in the extrusion. Matt (around 10–15% gloss) is flatter, more convincingly steel-like, and far more forgiving. It is what most architects specify and it is what makes a heritage profile actually pass for Crittall.

It depends on the wall. Black gives maximum contrast and suits white render, pale brick and stone. On dark red brick, black windows can read as holes in the elevation — anthracite grey (RAL 7016) recedes and usually looks better. Hold a sample against the actual wall in daylight before you decide.
The frame surface does absorb more solar heat, which is one reason powder-coat suppliers use higher-spec pigments for dark colours. It has no practical effect on the room temperature — the glass, not the frame, controls solar gain.
Matt, in almost every case. Gloss black shows rain streaks and surface imperfection badly. Matt reads more like steel and is far more forgiving.
