dont try so hard to be "dark". realistically drowning at the bottom of the ocean would be much darker. 1. fire emitts large amounts of light 2. no light reaches the bottom of the ocean 3. water absorbs light, not gives it off
4. water is a cool color in hue, fire is a hot color. cool colors are darker than hot ones.
while drowning would be much more pleasant and calming(provided you wereng stressing and flipping out), i would rather burn. wether i would choose that because of hydrophobia, pyrophilia, ignorance, stupidity, the insatiable desire to scream inhumanly, masochism, boredom, or any other reason, i dont know. i just think i probably would.
