I have a green fleur that I love. I'm cursed with whatever body chemistry that leads to easy staining. I can get MOST of the staining off with hydrogen peroxide soaks and a good scrubbing with a washcloth, but some just won't come off even with sunning. I'm looking to buy a second cup. I'm eyeing the large ladycups. Which colors hide staining the best? Maybe a bright yellow or dark purple?
