Whispering Wives. SHHhhh

Questions questions questions? We all need Answers! But some of us find Stories in Films and on Tv Harder to follow than most, when the main Plot devices deal with different Colours! Yes, i'm Colour Blind... When i first went to see Prometheus with the Miss's, i really wanted to ask her what the colour of that Stuff was and what the colour of the other Stuff was! But as i don't like to spoil Films for others whenever i go, i didn't ask her as i HATE it when other people talk when i'm watching a Film! One cannot be a hippocrite now! I did ask the Wife about the Colour of the different substances, after the Film had ended and her reply was....I CAN'T REMEMBER! lol My mates are not interested in going to the Pictures (Cinema)? (i know, they don't know what they're missing!) So if anyone can give me answers to the following questions, i would appreciate it! 1) What colour was the Substance that the Engineer drinks at the intro? I saw somethin Black but there was a Ting of another Colour? I heard somebody else say that ting was Gold? 2) What Colour is the Substance in the Tubes that David pulls out of the Ampule? I know the stuff at the botton is Black but what is the rest? Is it just Black? 3) What colour is the substance in the Pot, at the alter, under the Deacon Mural that Holloway? Takes an interest in? I think that's it...I really should have ask this in June when i saw it! But a Derrrr..on my part!
