On page 10 of the rules it says "Value: The value of a card is its age number. If a card refers to the value of something you don’t have, like your top purple card if you have none, treat the value as 0."
So if I use the dogma effect of Perfume, "I DEMAND you transfer a top card of different value from any top card on my board from your board to mine! If you do, draw and meld a card of equal value!" when I have no purple cards, shouldn't my opponent have to give me their purple card of value 1 since 1 is greater than 0?
