What to use for AttributeName in Xamarin Mac

Issue

I'm trying to colorize a substring in my NSMutableAttributedString in Xamarin, but it seems to be missing the proper constants,

What should I put there?

Update. This gets closer:

var s = new NSMutableAttributedString ("hello");
s.AddAttribute (CTStringAttributeKey.ForegroundColor , NSColor.Red, new NSRange (0, 3));
wordLabel.AttributedStringValue = s;

and gives

though the color on screen is still black text!

Update2 Maybe CTStringAttributeKey is the wrong one, but there is no NSStringAttributeKey

Solution

Ok, so I looked at the API and it seems it's there, just under NSAttributedString

ForegroundColorAttributeName

So use something like:

s.AddAttribute(NSAttributedString.ForegroundColorAttributeName, NSColor.Red, new NSRange(0,3));
