Properties related to the color enhancement effect, a postprocessing technique that provides
HDR-aware adjustments for shadows, highlights, vibrance, and dehaze. Shadows and highlights allow
selective adjustment of dark and bright areas of the image, vibrance is a smart saturation
that boosts less-saturated colors more than already-saturated ones, and dehaze removes atmospheric
haze to increase clarity and contrast.

## Properties

### dehaze

```ts
dehaze: number
```

The dehaze adjustment, -1 to 1 range. Positive values remove atmospheric
haze, increasing clarity and contrast. Negative values add a haze effect. Defaults to 0.

### enabled

```ts
enabled: boolean
```

Whether color enhancement is enabled. Defaults to false.

### highlights

```ts
highlights: number
```

The highlight adjustment, -3 to 3 range. Uses an exponential curve
where -3 gives 0.125x, 0 gives 1x, and +3 gives 8x brightness on bright areas. Defaults to 0.

### midtones

```ts
midtones: number
```

The midtone adjustment, -1 to 1 range. Positive values brighten
midtones, negative values darken midtones, with shadows and highlights more strongly preserved
than by a linear exposure change. Defaults to 0.

### shadows

```ts
shadows: number
```

The shadow adjustment, -3 to 3 range. Uses an exponential curve where
-3 gives 0.125x, 0 gives 1x, and +3 gives 8x brightness on dark areas. Defaults to 0.

### vibrance

```ts
vibrance: number
```

The vibrance (smart saturation), -1 to 1 range. Positive values boost
saturation of less-saturated colors more than already-saturated ones. Negative values desaturate.
Defaults to 0.
