I think it is possible since clDefault is TColor($20000000) and clBlack 
is TColor($000000) there are situations where the most significant bits 
of clDefault are lost and the two colours become identical.
I've found that the Object Inspector's default component editor for 
colours seems at times to initialise colours to $000000 whatever the 
component's constructor may have directed.
In these situations I've resorted to overriding the Loaded method to set 
the desired value.
