As I look at this further, it appears that FusionPro is using the gray value of the color to cast the darkness of the shadow.
In my opinion, this is a wrong way to approach this.
Why would solid cyan type cast a lighter shadow that solid magenta type?
If light where hitting solid cyan and solid magenta type in the same area, wouldn't the letters cast the same value of black in the drop shadow?
Thank you,
