solution 1:

-(void)awakeFromNib
{
    NSColor *color = [NSColor greenColor];
    NSMutableAttributedString *colorTitle = [[NSMutableAttributedString alloc] initWithAttributedString:[button attributedTitle]];
    NSRange titleRange = NSMakeRange(0, [colorTitle length]);
    [colorTitle addAttribute:NSForegroundColorAttributeName value:color range:titleRange];
    [button setAttributedTitle:colorTitle];
}

solution 2:

in *.m file:

- (void)setButtonTitleFor:(NSButton*)button toString:(NSString*)title withColor:(NSColor*)color
{
    NSMutableParagraphStyle *style = [[NSMutableParagraphStyle alloc] init];
    [style setAlignment:NSCenterTextAlignment];
    NSDictionary *attrsDictionary = [NSDictionary dictionaryWithObjectsAndKeys:color, NSForegroundColorAttributeName, style, NSParagraphStyleAttributeName, nil];
    NSAttributedString *attrString = [[NSAttributedString alloc]initWithString:title attributes:attrsDictionary];
    [button setAttributedTitle:attrString];
}

-(void)awakeFromNib
{
    NSString *title = @"+Add page";
    NSColor *color = [NSColor greenColor];
    [self setButtonTitleFor:button toString:title withColor:color];
}
