# HMCharacteristicTypeColorTemperature

The color temperature of a light.

## Declaration

```swift
let HMCharacteristicTypeColorTemperature: String
```

## Discussion

Discussion The corresponding value is an integer representing the color temperature in micro-reciprocal degrees (mired), which is 1,000,000 divided by the color temperature in kelvins. For example, to emulate a traditional tungsten light with a color temperature of 3200 K, use a mired value of about 312.
