my Ingame name is The_Engine and im playing IC2 right now and i realized that the bio cells and the biofuel cells have the exact same texture. in other words its very hard to distiguish bettween bio cells and biofuel cells (aside from the ingame name of said item).
so what im thinking is just make the biofuel cell some what darker than the bio cell.
this way it would be easier to determine which is which without hovering over the icon
