# getComponents(_:) Returns the components of the color as an array. ``` func getComponents(_ components: UnsafeMutablePointer) ``` ## Parameters `components` An array containing the components of the color object as `float` values. ## Discussion You can invoke this method on `NSColor` objects created from custom color spaces to get the individual floating-point components, including alpha. Raises an exception if the receiver doesn’t have floating-point components. To find out how many components are in the `components` array, use the [`numberOfComponents`](/documentation/AppKit/NSColor/numberOfComponents) property. ## See Also [`colorSpace`](/documentation/AppKit/NSColor/colorSpace) The color space associated with the color. --- Copyright © 2026 Apple Inc.
