	What color does the block pen start out in?

	     ^^  This is redundant; MOVEQ implies .l

	You're feeding 15,15,15 to the block pen.  If you're using the
default WorkBench colors, the block pen (which is what the WorkBench
screen's titlebar is drawn with) is *already* 15,15,15.  So it would be
unsurprising that you wouldn't see a change.  Try different values and see
what happens.
