# colorEffect(_:isEnabled:)

Returns a new view that applies shader to self as a filter effect on the color of each pixel.

## Declaration

```swift
nonisolated func colorEffect(_ shader: Shader, isEnabled: Bool = true) -> some View

```

## Parameters

- `shader`: The shader to apply to self as a color filter.
- `isEnabled`: Whether the effect is enabled or not.

## Return Value

Return Value A new view that renders self with the shader applied as a color filter.

## Discussion

Discussion For a shader function to act as a color filter it must have a function signature matching: [[ stitchable ]] half4 name(float2 position, half4 color, args...) where position is the user-space coordinates of the pixel applied to the shader and color its source color, as a pre-multiplied color in the destination color space. args... should be compatible with the uniform arguments bound to shader. The function should return the modified color value. important: Views backed by AppKit or UIKit views may not render into the filtered layer. Instead, they log a warning and display a placeholder image to highlight the error.
