Triadic Coast Blue

Triadic Coast Blue has a deep, cool slate-blue ground crossed by tightly packed blue-grey angular lines. The small repeating zigzag weave gives the surface a precise, graphic rhythm without overpowering its dark tone.

About this fabric

This heavyweight fabric weighs 738 gsm and has a dense construction of 73 threads per cm, making it a strong choice for upholstered seating. Its compact geometric pattern repeats every 9.1 cm vertically and 7 cm horizontally, creating an even chevron-like texture across the cloth. The dark blue ground absorbs the light, while the lighter woven lines pick out the pattern with a subtle, dimensional contrast. It is supplied at a usable width of 139 cm, with a standard length of 25 m.

How to use it

Use this cool slate-blue colourway on a structured armchair, sofa or dining seat where its small-scale geometry can read as texture from a distance. Balance the dark woven ground with warm oak, chalky neutrals or muted blue-grey accents.

Pair the deep slate-blue ground with pale timber, charcoal or brushed metal for a cool, tailored scheme.

A pattern needs somewhere for the eye to rest, so these are the plains and textures that sit beside Triadic Coast Blue without fighting it. Mixed across the houses we hold, which is the part a single supplier's book cannot do.

Paint that goes with it

Two ways to take the room. Both colours are from houses we hold, so a pot can come off the same order as the cloth. Screens shift colour, so treat these as a direction and bring the cloth to the shelf before you buy the paint.
