# SRAmbientLightSample.Chromaticity

A coordinate pair that describes light brightness and tint.

## Declaration

```swift
struct Chromaticity
```

## Overview

Overview The SRAmbientLightSample class provides read-only access to an instance of this structure through its chromaticity property.

## Topics
