The green aqua NEGMCO beehive in the middle is an unlisted color for this manufacturer. I have all of the other green shades listed for NEGMCO beehives and this one doesn't match any of them. The beehive on the left is aqua and on the right is true green. Wouldn't you think that green aqua would be a color listing for all glass houses that made aqua and green insulators? After all, I doubt transition between these colors was perfect.
