# init(colorSpace:components:count:) Creates a color object from the specified components of the given color space. ``` init(colorSpace space: NSColorSpace, components: UnsafePointer, count numberOfComponents: Int) ``` ## Parameters `space` An `NSColorSpace` object representing a color space. The colorspace should be component-based. The method raises if this is `nil` or a color space that cannot be used with `NSColor` objects. `components` An array of the components in the specified color space to use to create the `NSColor` object. The order of these components is determined by the color-space profile, with the alpha component always last. (If you want the created color to be opaque, specify 1.0 for the alpha component.) `numberOfComponents` The number of components in the `components` array. This should match the number dictated by the specified color space plus one for alpha. This method raises an exception if they do not match. ## Return Value The color object. ## See Also [`usingColorSpace(_:)`](/documentation/AppKit/NSColor/usingColorSpace(_:)) Creates a new color object representing the color of the current color object in the specified color space. --- Copyright © 2026 Apple Inc.
