Actually, the sensitivity peaks for the visual receptors are roughly violet, green, and yellow-green, with significant overlap between the last two, it's just that rgb is good at getting the three receptors to each fire at the right ratios.

If you're going to split visible light into seven logical hues, you'd likely just use fixed segments of the rainbow, which gives you something like
  • 420nm (Near-Indigo)
  • 460nm (Near-Blue)
  • 500nm (Near-Cyan)
  • 540nm (Near-Lime)
  • 580nm (Near-Yellow)
  • 620nm (Near-Orange)
  • 660nm (Red)
