# setColorByTemperature(_:)

Sets the light’s color based on a black-body temperature.

```
func setColorByTemperature(_ temperature: Float)
```

## Parameters

`temperature`

The black-body temperature, in Kelvins, whose luminous color the light should match.

## Discussion

Real-world light sources often measure color of illumination based on a black-body temperature scale. For example, the colors and characterizations of typical home and office light fixtures correspond to the following temperatures:

|Label          |Color                          |Temperature|
|---------------|-------------------------------|-----------|
|“Soft white”   |Warm, yellowish white          |2700 K     |
|“Bright white” |Pale yellowish white           |3000 K     |
|“Daylight”     |Bright, slightly greenish white|5000 K     |
|“Cool daylight”|Bright, slightly bluish white  |6500 K     |
