Lines 30 to 32 in 8fa7967

// (116.892405498713, 251.242468747889, 129.109129531237)/255
// Quantized to 8-bit, this is:
// (116, 251, 129) 

  // Converted back to Display P3 this is:
  //   (116.892405498713, 251.242468747889, 129.109129531237)/255
  // Quantized to 8-bit, this is:
  //   (116, 251, 129)
