How to compare colors in iOS -

-

I need to compare one color to another with an array of colors and determine which other colors Is most seeming.

I do not know a lot about color theory, I think L * A * B * is a colorpace that is most used to compare the colors, perhaps using the delta metric , But I also believe that this color space is not supported in iOS.

I know to get color in HSV or RGB, but I do not know that they can be transformed into L * A * B * colorspace program or if a method of cruel power is to be used in other colors One of the colors is compared which is supported by iOS

Any help will really be appreciated.
