A light is charted simply as 'Fl 6s' with no color designation. What color is this light?

  1. A. Green, as green is the default channel color
  2. B. Red, as red is the most visible color at sea
  3. White, as white is the default and is omitted from the characteristic stringCorrect
  4. D. Yellow, as yellow indicates a special-purpose aid

Why C is correct

White is the default light color and is omitted from the characteristic string when the light is white. A charted 'Fl 6s' with no color suffix is therefore a white flashing light. (Light List — W)
