# init(red:green:blue:alpha:linearExposure:)

Generates an HDR color by applying an exposure to the SDR color defined by the red, green, and blue components. The `red`, `green`, and `blue` components have a nominal range of [0..1], `linearExposure` is a value >= 1. To produce an HDR color, we process the given color in a linear color space, multiplying component values by `linearExposure `. The produced color will have a `contentHeadroom` equal to `linearExposure`. Each doubling of `linearExposure` produces a color that is twice as bright.

```
init(red: CGFloat, green: CGFloat, blue: CGFloat, alpha: CGFloat, linearExposure: CGFloat)
```
