The brightness adjustment 'b 1' always sets the brightness all the way to white (or to a color if the saturation is greater than zero). 'b -1' always sets the brightness to black. What you need is two rules. Your AA rule will fade from white to black, but you need to start with another rule (let's call it AB), that changes the color from the default black to white:

Code: Select all

startshape AB 

rule AB 
{
AA {b 1}
}

rule AA 
{ 
CIRCLE{} 
AA{x .8 s .9 b -0.05} 
}
