This is just the problem, you need version 4.2. Code "lc rgb 'green'" is
not recognized by gnuplot 4.0. In the first versions of 'draw', colors
were controlled by numeric indices, but I think it's more friendly to
allow color names (things like color="#325af7" are also possible).
Type ? color

I understand. That would be of great help.
