In the middle of the Great Plague, a young Isaac Newton sat alone in his dorm room and uncovered one of the most fundamental truths about light: white light is made of all colors combined. That revelation sparked centuries of exploration into color, what it is, how we see it, and why it affects us so profoundly. From prisms and rainbows to the rare ability of tetrachromacy, the story of color is as much about human perception as it is about science. And as it turns out, our eyes and brains aren’t neutral observers. They constantly adjust, balance, and even deceive us, shaping the way we experience the world.   Color doesn’t just decorate an image—it directs emotion, creates contrast, and even alters what we see next. After-images, color constancy, and complementary hues aren’t abstract concepts; they’re powerful tools filmmakers use every day to guide attention and amplify feeling. From professional color grading suites to unforgettable films like Raise the Red Lantern, color becomes the hidden hand shaping what an audience feels. This episode uncovers how light, perception, and artistry converge, showing why mastering color is essential for anyone who works with images.
