# pinLightBlendMode()

Blends colors of two images by replacing brighter colors.

## Declaration

```swift
class func pinLightBlendMode() -> any CIFilter & CICompositeOperation
```

## Return Value

Return Value The modified image.

## Discussion

Discussion This method applies the pin-light-blend mode filter to an image. The effect calculates the brightness of the colors in the background image. Colors that are lighter than 50 percent gray remain unchanged, while the filter replaces colors that are darker than 50 percent with the corresponding color values of the input image. The effect then uses the calculated result to create the output image. The pin-light-blend mode filter uses the following properties: The following code creates a filter that results in the image becoming darker with more saturation and the colors of the gradient image: func pinLightBlendMode(inputImage: CIImage, backgroundImage: CIImage) -> CIImage {     let colorBlendFilter = CIFilter.pinLightBlendMode()     colorBlendFilter.inputImage = inputImage     colorBlendFilter.backgroundImage = backgroundImage     return colorBlendFilter.outputImage! }
