Colour temperature chart: every common light source in Kelvin

A printable Kelvin reference for every light you are likely to meet, from candle flame at 1800K to deep blue sky past 10000K, with the camera setting that matches each.

Every light you are likely to point a camera at, with its approximate colour temperature and the camera setting that matches it. Treat these as starting points - real sources vary widely, and the chart cannot tell you anything about tint.

The scale is linear in Kelvin. Note how much of it sits above 5500K - "cool" covers a far wider numeric range than "warm".

The full chart

Kelvin Source Looks Camera setting
1700K Match flame Deep amber Rarely balanced; shoot it as a warm accent
1800K Candle flame Deep amber 1800-2000K if you want candle to read white
2000K High-pressure sodium street light Amber, heavy green tint Often better left uncorrected
2200K Vintage / Edison filament bulb Warm amber 2200K
2500K Dimmed incandescent Golden orange Meter it; dimming shifts it
2700K “Soft white” household LED or bulb Warm yellow 2700K
2800K Standard incandescent Warm yellow 2800K
3000K “Warm white” bulb Warm neutral 3000K
3200K Studio tungsten / halogen Yellow-orange 3200K - the tungsten anchor
3500K Warm fluorescent Pale yellow 3500K, plus magenta tint
4000K “Cool white” / office fluorescent Pale neutral 4000K, plus magenta tint
4300K Sunrise, one hour after Warm neutral Meter; changes fast
4500K Cool fluorescent, moonlight Near-neutral 4500K, plus magenta tint
5000K Horizon daylight, “daylight” bulbs Slightly warm white 5000K
5500K Midday sun, camera flash, daylight LED Neutral white 5500K - the daylight anchor
5600K HMI, cinema daylight standard Neutral white 5600K
6000K Bright overcast Slightly blue 6000K
6500K Cloudy daylight, monitor white point (D65) Cool blue 6500K
7000K Heavy overcast Blue 7000K
7500K Open shade on a sunny day Blue 7500K
8000K Deep shade, blue hour Strong blue 8000K, or leave blue on purpose

By category

Household and practical lighting

Marked on the box Kelvin Typical room
Soft white 2700K Living rooms, bedrooms
Warm white 3000K Kitchens, bathrooms
Cool white / neutral 4000K Offices, garages
Daylight 5000K Workshops, retail
Cool daylight 6500K Clinical spaces, grow lights

If you are dressing a set, buy every practical in a room at the same Kelvin. Mismatched bulbs in one frame is the most common reason a shot will not grade cleanly, and it costs nothing to avoid at the shop.

Film and video lighting

Fixture Kelvin Note
Tungsten fresnel 3200K Drops as it dims
HMI 5600K Can shift 400K in its first minutes - meter it hot
Daylight LED panel 5600K Check tint; cheap panels skew green
Bi-colour LED 2700-6500K Set it to the practicals, not to a round number
Kino Flo tube 3200K or 5500K Sold in both, clearly labelled
Studio strobe 5500K Tuned to D55 so it matches sun

Daylight through the day

Time Kelvin Note
Pre-dawn / blue hour 8000-10000K Correcting it fully removes why you got up
Sunrise 2000-3000K Shifts roughly 200K every five minutes
Mid-morning 4500-5500K Settling toward the reference
Midday, clear 5500K The anchor
Overcast, any hour 6000-7000K Flat and cool
Open shade 7000-7500K Lit by sky, not sun - much cooler than it looks
Golden hour 3200-4500K, falling Re-meter every few minutes
Sunset 2000-3000K As above, faster

What a chart cannot tell you

Two things, and both matter more than people expect.

Real sources deviate from nominal. Two bulbs from the same box can differ by 200K. A tungsten lamp on a dimmer drops several hundred Kelvin between full and half. An HMI shifts as it warms. A bounce off a cream ceiling adds a few hundred Kelvin of warmth, off a wooden floor closer to a thousand. The chart says what the source is meant to be, not what it is doing in your room.

A chart says nothing about tint. Colour temperature is one axis. The magenta/green axis is the other, and it is the one that makes a fluorescent-lit interview look ill. You can set 4000K exactly right on an office tube and the footage will still be green, because green is not a Kelvin problem.

That is the whole argument for metering rather than looking things up: you get the number this light is actually producing, and you get the tint alongside it.

Using the chart properly

  1. Estimate from the chart to get in the right neighbourhood.
  2. Meter to confirm - KEV reports Kelvin and tint through the iPhone camera in real time.
  3. Enter both in the camera’s manual white balance.
  4. Verify on a grey card before you commit the setup.

The chart is for when you have no meter and need a defensible starting point. It is not a substitute for the number the room is actually producing.

Frequently asked questions

What is a colour temperature chart?

A colour temperature chart lists common light sources against their approximate value on the Kelvin scale, so you can estimate a white balance setting without metering. Candle flame sits near 1800K, tungsten bulbs near 2800-3200K, midday sun near 5500K and open shade near 7500K.

What Kelvin is daylight?

Direct midday sun on a clear day is about 5500K, which is the D55 reference that flashes and daylight-balanced LEDs are tuned to. Daylight including sky is nearer 6500K (D65). Overcast runs 6000-7000K and open shade, lit by blue sky rather than the sun, reaches 7000-7500K.

What Kelvin is a normal light bulb?

A soft white incandescent bulb is about 2700-2800K. Studio tungsten and halogen are standardised at 3200K. A dimmed incandescent drops sharply as it dims, often several hundred Kelvin between full and half brightness.

Is a colour temperature chart accurate enough to skip metering?

For a rough starting point, yes. For anything colour-critical, no. Real sources vary widely from their nominal value: two bulbs from the same box can differ by 200K, and a chart cannot tell you the tint at all, which is what makes fluorescents and cheap LEDs look green.

What is the difference between 3200K and 5600K lighting?

They are the two standard anchor points. 3200K is tungsten-balanced, the warm orange of studio lamps and household bulbs. 5600K (often rounded to 5500K) is daylight-balanced, matching midday sun, HMI and daylight LED. Film stock, sensors and lighting kit are all designed around this pair.
