fluid1.getColor() = 2013252778 => ‭0111 0111 1111 1111 1100 1100 1010 1010‬ => 4 bytes
fluid2.getColor() = -263978855 => ‭1111 1111 1111 1111 1111 1111 1111 1111 1111 0000 0100 0100 0000 0000 1001 1001‬ => 8 bytes

with the first number: red = n; green = n >> 8; blue = n >> 16; alpha = n >> 24
Since the second has 8 bytes, am I right to assume this? red = n; green = n >> 16; blue = n >> 32; alpha = n >> 48

Also, since I'd like my renderer to work with any fluid, I'm sure there's a way to have the mod compute the number of bytes of each Integer and evaluate the shifts?
