The food colouring

So, halloween is approaching and curious as ever, I wondered what would happen if I emptied an entire bottle of black food colouring into a Victoria sponge cake mix. Obviously I knew the cake would turn out some shade of dark. But is it possible to find black cake not only visually pleasing but edible? Answer. No. And to further the level of grossness I mixed a gloriously grotesque shade of orange into butter icing and slapped it on top of the cakes. Wow.
