# getCyan(_:magenta:yellow:black:alpha:) Returns the color object’s CMYK and opacity values. ``` func getCyan(_ cyan: UnsafeMutablePointer?, magenta: UnsafeMutablePointer?, yellow: UnsafeMutablePointer?, black: UnsafeMutablePointer?, alpha: UnsafeMutablePointer?) ``` ## Parameters `cyan` Upon return, contains the cyan component of the color object. `magenta` Upon return, contains the magenta component of the color object. `yellow` Upon return, contains the yellow component of the color object. `black` Upon return, contains the black component of the color object. `alpha` Upon return, contains opacity value of the color object. ## Discussion If `NULL` is passed in as an argument, the method doesn’t set that value.
