+**CMYK Array & Dictionary to and from a UIColor**
+
+Like both of the RGBA methods above, you can also get the CMYKY values from a UIColor and create an array or dictionary out of them, or vice versa. The colorDictionary returned also uses static keys like the RGBA version of this method. Here are the ones to use:

+* `kColoursCMYK_M`
+* `kColoursCMYK_Y`
+* `kColoursCMYK_K`

-This method returns a dictionary containing values for each of the keys (RGBA, HSBA, CIE_LAB) from above. This means you can get a hue value and a Lightness value from the same source. Here's how you use this:

+You can also retrieve singular values instead of the entire dictionary by calling any of these methods below on a UIColor. This will be significantly slower at getting all of the values for one color, versus just retrieving one. If you need more than one, call the specific array or dictionary method from above.
