Do I need to release CGColorSpaceRef under ARC?

Let's say I have this piece of code:

CGColorSpaceRef colorSpaceRGB = CGColorSpaceCreateDeviceRGB();

CGContextSetStrokeColorSpace(context, colorSpaceRGB);
CGContextSetFillColorSpace(context, colorSpaceRGB);

After that I do some drawing. When I'm done, do I need to manually release colorSpaceRGB if I'm using ARC? Like this:

CGColorSpaceRelease(colorSpaceRGB);

Or I don't need to do anything?

Thanks :)

Update for Swift 4.0:

This is no longer needed in current versions of Swift. 

CGColorSpaceRelease(colorSpace)

This line of code now gives the following message:

'CGColorSpaceRelease' is unavailable: Core Foundation objects are automatically memory managed

Yes. According to Apple's doc: Because CGColorSpaceRelease function is equivalent to CFRelease, except that it does not cause an error if the cs parameter is NULL. And if you create, copy, or explicitly retain a Core Foundation object, you are responsible for releasing it when you no longer need it (see Memory Management Programming Guide for Core Foundation).

Yes, I believe so, even under ARC.

You need to call CGColorSpaceRelease as per the documentation CGColorSpace Documentation.
