Landmarks, colour and wayfinding.

In the public realm, light makes landmarks, guides people and gives a place identity after dark — and it has to survive the weather and the years. Rosco tools bring permanent dichroic colour, projected wayfinding and pattern, and rugged accent light to squares, bridges, artworks and civic spaces.

The brief

Identity, guidance and endurance

Public spaces ask a lot of light. It has to give a place a night-time identity, help people find their way, sometimes become the artwork itself — and do all of it through weather, vandalism risk and years of continuous operation, with colour that never fades and hardware that keeps working.

Rosco’s permanent-grade toolkit suits this duty. Permacolor dichroic glass holds saturated colour indefinitely; custom gobos project wayfinding and pattern that reconfigure without physical signage; and rugged, compact fixtures deliver accent and wash at scale.

What we bring

Built for the public realm

Permanent colour

Permacolor dichroic glass gives landmarks and artworks a saturated colour identity that doesn’t fade.

Projected wayfinding

Custom gobos project paths, icons and pattern onto pavements and surfaces — reconfigurable, no signage.

Rugged accent

Compact, robust fixtures accent structures and features and hold up to continuous outdoor duty.

Reference project

Colour on a 90-ft ring

Montreal’s L’Anneau uses custom Permacolor dichroic filters — amber, pink and Mediterranean blue — with custom glass gobos, lighting only the inner contour of a giant steel ring in a public square.

A permanent public artwork where the colour has to look immaculate every night, for years — exactly the endurance the public realm demands.

Designing it in

What to plan for

Public projects live outdoors for years. CFATS confirms durability, colour and control for the environment and the duty.

Environment & ingress

Weather, temperature and access affect fixture and mounting choice; we specify for the real conditions.

Permanence of colour

Permacolor dichroic glass avoids the fade and replacement cycle of gels in exposed installations.

Spill & obtrusive light

We plan masking and shaping to respect neighbours, the night sky and local lighting guidance.

Maintenance & access

Fixture positions and serviceability are planned for the realities of a public site.
