Offset = 100
set linetype Offset   lc rgb 'black'
set linetype Offset+1 lc rgb 'red'
set linetype Offset+2 lc rgb 'blue'
...

plot 'Data.out' ... using ($1):($2):(column(-2) + Offset) ... lc variable

DarkCyan = 0x00DDDD               # Not sure this works on windows
set linetype Offset+3 lc rgb DarkCyan

but also see "show colors"
