Sodium sulfide and aluminium metal reaction
Yesterday, I bought some Na2S. Since I heard I was a strong base I wondered if it would act like NaOH on aluminium. So I made a concentrated solution
and added aluminium foil. It reacted similar to aluminium and cold sodium hydroxide solution(although it heats up quick) and produces a really dark
green solution. I'm assuming it's some kind of aluminium oxide sodium sulfide complex or something, since The reaction is similar to sodium hydroxide
and aluminium producing NaAlO2(or NaAl(OH)4)

It's probably black, as opposed to green. However, a black substance mixed with a yellow substance will often look dark green, and since elemental
sulfur seems like one likely product of this reaction, that could explain the yellow.
I'm not sure why you're not considering aluminum sulfide species? Sodium doesn't really like being bonded to sulfide, or the rest of the elements in
that group, for that matter.
The first step in the process of learning something is admitting that you don't know it already.

Maybe so, I didn't consider Aluminium sulfide because it seems to be be unstable in water and hydrolyzes forming H2S.
