: Put a charge counter on Jeweled Amulet. Note what type of mana was used to pay this activation cost. Play this ability only if there are no charge counters on Jeweled Amulet.

, Remove all charge counters from Jeweled Amulet: Add one mana of the type last used to put a charge counter on Jeweled Amulet to your mana pool. Play this ability only if there are one or more charge counters on Jeweled Amulet.
You are right... BUT, suppose we use the first ability to put a charge counter (and doing this we take note of the color used, let's say blue), then later we use the second ability to get the mana.
Later in the game, we use some card to move a charge counter to the amulet. If we then use the second ability, wouldn't we get a mana of the last color chosen (in this case blue), since it reads "Add one mana of the type last used to put a charge counter on Jeweled Amulet to your mana pool"? Even if the card refers to the color used, it does not refer to the color used for the counter we are removing, but just to the color used
the last time we put a charge counter chosing a color.
I'm climbing mirrors, I know...
