Every Lighting story on the Moodroom blog.
The greige that matched the floor under the shop lights turns pink at home because a colour match belongs to the light it was made under. Metameric failure explains why finishes drift apart once installed, and how to choose a palette that holds.

A harsh room is rarely over-lit; it is a small, blazing source set against a dark surround near your line of sight. Discomfort glare is a luminance ratio, which is why shielding the source and lifting the background beat reaching for the dimmer.
A dimmed incandescent bulb does not just get darker, it slides toward amber candlelight. Here is why a standard LED cannot follow it, and what dim-to-warm actually does.
Horizontal desk lux is the wrong yardstick for how bright a room looks. Perceived brightness and spaciousness come from the light your vertical surfaces throw back — which is why washing the walls can make a room read several times brighter and visibly larger without adding a single lumen.
A bright, code-compliant office can still leave its occupants under-lit for their body clock, because circadian health is set by melanopic light at the eye: vertical, blue-weighted, and unrelated to the lux measured flat on the desk.
A paint or fabric that matched perfectly in the store can turn lilac by morning and green by lamplight. The culprit is metamerism, and it means colour is never a fixed property of the wall.
Biophilic rooms keep counting plants and square metres of glass, but the part of a natural scene that actually calms a tired mind is the movement of light. Here is why non-rhythmic, dappled light is the active ingredient, and how to build it without a motorised facade.
Flat LEDs broke the century-old link between dimming down and warming up. Dim-to-warm welds colour back onto the dimmer, tracing candlelight on a single channel where tunable white cannot follow.
Conventional offices are judged by lux on the desk, but the body's clock reads light at the eye. The circadian shift replaces horizontal illuminance with vertical melanopic EDI -- and exposes how dark a well-lit room can be.
For a decade motion sensors have switched the lights off on anyone who dared to sit still. In 2026 mmWave radar that reads the rise of a breathing chest, now standardised through Matter, finally lets a room's light follow presence instead of movement.
