Highlight Blue?

Does anyone know what Ereplacementparts is referring to when they list "Highlight Blue"?

In the link above, they show a number of lids (No. 5).  Burgundy, black, blue, dark blue, highlight blue and green.  Unfortunately, no pic.  Just curious if anyone here has any idea.

Dunno. I thought the blue SJ's in Europe were called Blue Wave? Is it possible the full size ones have a different color designation?
