is it a bug or a feature?

[Lloyd Dupont]

if I use predefined color, such as

 

NSColor* c = [NSColor blackColor];

 

it will return a GSCalibratedWhiteColor which is a light subclass of NSColor.

therefore, later, when I call

 

[c getRed:&red green:&green blue:&blue alpha:&alpha]

 

I get the default behavior, which is:

 

  [NSException raise: NSInternalInconsistencyException
       format: @"Called getRed:green:blue:alpha: on non-RGB colour"];

 

A bit annoying....

So now I wonder should I:

 

1. consider this a bug and try to fix it?

2. consider this a feature and stop using named color?
