Color Drop Quiz is a color prediction game you can play with one thumb. Four bottles hang above a glass flask — red, yellow, blue and white pigment, the classic primaries you remember from art class plus a flask of paper white for honest pastels. In Quiz mode the lab drips a secret recipe drop by drop, and your job is to predict the resulting mixture before the liquid settles. Colors mix the way paint does in the real world: red and yellow bend toward orange, yellow and blue become green, white tints everything toward pastel, and if you get greedy and mix all three chromatics you will brew a muddy brown nobody wants. Answer fast to stack speed bonuses and streak multipliers; three misses and the run is over. Every correct prediction is added to your codex with a procedurally generated name and a rarity, from common house serums to legendary one-in-a-hundred elixirs. Every day the lab publishes a global five-round Daily Quiz that is identical for every player on Earth — answer it, score it, and compare your rank with players around the world.
