Basically its a magic sheet with 2 layers to it you got an array of channels that are set to colors you want that are linked to intensity of any channels you want (I suggest very big numbers so they don't interfere with other things) then you have a layer of macros on top so when you pick them over lapping it executes the macro then you simply set each macro to set all intensity that are in the color row to 0 set the fixtures to your color then set the channel that the macro is placed on top to 100. for The all function just have it execute a set all channels in the row to 0 intensity have it execute all macros that would change the color of each group and have set intensity of channel sitting under macro to 100. BAM your done
