Color science sits at the intersection of physics, biology, and art. Light is electromagnetic radiation, but color is a perception — constructed by our brains from cone cell signals. Understanding this distinction unlocks everything from display technology to accessible design to the physics of starlight.
These simulations let you mix colors additively and subtractively, experience what the world looks like through color-blind eyes, decompose light into spectral components, explore black body radiation and color temperature, and discover why certain color combinations feel harmonious. Manipulate wavelengths, adjust parameters, and see the science of color come alive.
