# init(colorGamutConversion:enableClampValues:)

Creates a color match using an explicit gamut conversion matrix.

## Declaration

```swift
init(colorGamutConversion: simd_half3x3 = matrix_identity_half3x3, enableClampValues: Bool = false)
```

## Parameters

- `colorGamutConversion`: A 3×3 matrix that converts RGB values from the renderer’s working color space to the output display’s color space. Defaults to identity.
- `enableClampValues`: If true, output values are clamped to [0, 1] after gamut conversion. Defaults to false.
