A match-4 game where the items you are matching aren't directly colored!

Click and drag a ball with your mouse to get started.

Each item is either Cyan,  Magenta or Yellow, but they only present themselves to you as black. However, when you swap two items, the background transforms into the composite color that is made from combining them.  Cyan + yellow = green, yellow + magenta = red and cyan + cyan = a cyan background. Use the handy key in the top right corner for reference.

Matching 4 of the same color clears them from the screen; but watch out, filling up your game board ends the game!

How many turns can you make it?
