Slate Blue
Pigment-dense and unapologetic — a wall colour, not an accent. On site, Slate Blue ends up most often in rendered façades. Pairs with pale oak, indigo textiles and matt-black ironmongery. Within the Ruboflex Exterior Coating range, Slate Blue carries a cool, slightly silvered character and blue-slate undertones — deep blue-grey for slate-style roofs in overall character. Borrows its character from coastal heritage interiors and re-reads them in a modern context.

Questions clients ask about this shade
Won't Slate Blue make the room feel smaller?+
Deep shades like Slate Blue actually blur a room's edges, making walls feel further away rather than closer. The trick is to wrap the colour onto skirting and trim so there are no high-contrast lines to remind the eye where the room ends.
How long does Slate Blue last on an exposed roof?+
The Ruboflex system carries a 10-year manufacturer guarantee under normal UK weather conditions. Slate Blue resists UV fade well — the pigment is locked into an elastomeric carrier rather than sitting on the surface.
What does Slate Blue pair with from your range?+
We most often pair Slate Blue with the three closest shades in its family — see the pairings panel below. Beyond that, it anchors well against pale plaster, white-oak floors and antique brass detailing.
