Hi,  
Im new to actionscript 3.0 and i saw that it can handle function called brightness.  
I want f/e to make a red circle which brightness i want to increase and decrease by 1 when I press uparrow and downarrow.  
It seems simple but I have problems with that.  
Can you help me please ?  
Thank you,
