Can you meet a rainbow need on Yummy with a Potion card?
One reply gives this reading, and the expansion rule is not in the base rulebook.

Yes. The rainbow bar takes the colour you chose, so the card you draw of that colour can be a Potion, which meets the need. You still discard a card of that colour at the end of the round.
