Magic potion... containers

Have you ever thought that some magic may not come from the magical potion, but from its container? I'm afraid that due to expendable nature of the potion container (bottle, flask, jar and soon) may lead to the missing of this phenomenon but well, it's players' problem, not mine :D

Here are some examples of the magical liquid containers, of course with fixed colors. Roll 1d20:

1. White. Turns the liquid to 40% alcohol, mainly vodka.
2. Blue. Turns the liquid into potion of healing.
3. Red. Turns the liquid to sauerkraut juice.
4. Yellow. Turns the liquid into urine.
5. Olive. Turns the liquid into vinegar. 
6. Brown. Turns the liquid into potion of invisibility.
7. Transparent. Turns the liquid into molten metal.
8. Green. Turns the liquid into potion of blindness.
9. Black. Turns the liquid into fresh water.
10. Violet. Turns the liquid into cheap, very sour wine.
11. Silver. Turns the liquid into blood.
12. Gold. Turns the liquid into poison (randomly determined).
13. Grey. Turns the liquid into ash (!).
14. Orange.Turns the liquid into somewhat diluted tree resin.
15. Dark-green. Turns the liquid into fruit juice (randomly determined).
16. Pink. Turns the liquid into potion of paralysis.
17. Navy blue. Turns the liquid into potion of fire breathing.
18. Aquamarine. Turns the liquid into mustard.
19. Copper. Turns the liquid into potion of water breathing.
20. Dark-brown. Turns the liquid into potion of sleep.

After filling the container with liquid, it starts transforming its contents after 1d6 turns. Transformation ends after the next 2d6 turns.
