Colour Change
Lighting with full RGB colour control
Smart lights that shift across the full colour spectrum — red, blue, green and everything between. Mood scenes, entertainment integration, colour-themed rooms.
When full colour change earns its place
Most rooms don't need colour-change lighting — warm-to-cool white (tuneable white) handles everyday use better than RGB. But in specific situations, colour change is genuinely useful:
Kids' bedrooms — themed colour lighting (blue for a "space" scene, green for a jungle mood, pink for princess night) is genuinely delightful for younger children. Older kids set their own colours for homework vs play vs bedtime.
Entertainment spaces — TV rooms and home cinemas benefit from coloured back-wall lighting that syncs with the screen content or sets an atmospheric base. Reduces visual strain during long viewing sessions.
Party and hosting scenes — dim coloured lighting for entertaining, red-tinted warmth for late-night drinks, cooler blue or green for specific themes.
Accent and architectural lighting — coloured wall-washing or feature-lighting that changes with seasons, holidays, or room usage.
Circadian and wellness applications — very warm amber light in the evenings (below 2000K) is easier on sleep cycles than standard warm white. Some tuneable fittings cover this already, but colour-change fittings go further into the ultra-warm range.
RGB vs RGBW vs RGBWW — the spec to check
Not all "colour change" lights are created equal. The spec to check on the product page:
RGB — red, green and blue LEDs only. Can mix any colour, but "white" from RGB is greyish and less appealing than dedicated white LEDs. Cheaper colour-change fittings often have RGB only.
RGBW — RGB plus a dedicated cool white LED. White light is proper white; colours are still available. Better balance than RGB-only.
RGBWW (RGBCW) — RGB plus two white LEDs (warm and cool). Full colour range plus full tuneable white across 2700K–6500K. The most capable spec. Look for this if you want a colour-change fitting to double as your everyday warm-white lighting.
For most living-room and bedroom applications, RGBWW is the right spec. For decorative accent lighting where you want colour and don't care about white output, RGB is fine.
What about "colour temperature" vs "colour"?
Easy to confuse. Two different things:
Colour temperature — how warm or cool the white light is. Measured in Kelvin (2700K–6500K). Covered by tuneable-white fittings. See tuneable white.
Colour — the full RGB spectrum: red, blue, green, purple, etc. Covered by colour-change fittings (this category).
RGBWW fittings do both; RGB fittings only do colour.
Compatibility and control
Colour-change fittings work with:
Alexa and Google Home — voice commands like "Alexa, make the bedroom blue" or "Hey Google, set the living room to red". Most colour-change fittings support both assistants.
Companion apps — the brand's own app usually has the richest colour picker and scene-building tools. Wheel-based colour selection, gradient scenes, music-sync features.
Scene routines — tie colour-change into Alexa routines or Google Home actions: "good morning" sets the bedroom to warm amber, "movie night" sets the living room to dim red.
Entertainment sync — some colour-change systems (most notably Philips Hue's entertainment mode) sync light colour to on-screen content in real time. Adds atmosphere to films and games; requires specific hub configuration.
Frequently asked questions
Will colour-change lights work as everyday warm white?
Only if the fitting is spec'd as RGBW or RGBWW. RGB-only fittings can approximate white but the result is usually a greyish off-white, not a proper warm white. For colour-change lighting that also does good everyday white, pick RGBWW.
Are colour-change lights more expensive than tuneable white?
Yes — the extra LEDs and electronics cost more. RGBWW fittings typically sit 20–50% above equivalent tuneable-white-only fittings. Pick based on whether you actually need colour change; many homes don't.
Do colour-change bulbs fit standard lamps?
Yes — colour-change smart bulbs come in E27, E14, GU10 and most other standard caps. Swap a standard bulb for a colour-change smart bulb in any compatible lamp or fitting. See smart light bulbs.
Can I animate colour-change lights?
Most colour-change systems support gradient scenes that slowly shift between colours. Music-sync and entertainment-sync features animate in real time. Static-only colour lights (no animation) also exist at lower price points.
