Making green in the digital world (RGB or Hex codes) is even cleaner. You set your Red value to zero or low, and crank up the Green and Blue to high.
For example, Pure Green is 0, 255, 0. Screaming Lime? 100, 255, 50. Olive Drab? 85, 107, 47. The principle is the same—mixing light—but the result is brighter because you’re adding light, not subtracting it from a white paper.
