Leopard ignores setControlTint: ?

I have a number of controls set to be gray using code like:

  [[myControl cell] setControlTint: NSGraphiteControlTint];

in the appropriate  awakeFromNIb.

This worked fine on 10.3 and 10.4, but I just noticed Leopard 
(10.5.1) seems to ignore this and draw them in blue.  The behavior is 
the same whether the app is built on 10.4 or 10.5.

Has anyone else seen this or have any suggestions ?
