The patterns on the umbrella are made of hydrochromatic ink which changes colour when rain falls. The black and white umbrella becomes colourful the moment it rains. Hydrochromic ink is a kind of water based ink, which can change colour from white colour to transparent when it gets wet,and would return back to original colour when it gets dry,hydrochromic ink can be applied through screen printing
bahahaha! In all seriousness though, that is a super cool table! -- If this is just painted with thermochromic paint, could I, in theory just take my own table and paint it as well and get the same effect??
