Do you mean that you combine orange and blue, take the result and combine it with blue, take the result of that and combine it with orange? Yes, that would give a pretty good balance.

Orange = (½ red + ½ yellow + 0 blue); blue = (0 red + 0 yellow + 1 blue). Combine/average them to get → (¼ red + ¼ yellow + ½ blue)

Combine/average with blue (0 red + 0 yellow + 1 blue) again to get (⅛ red + ⅛ yellow + ¾ blue).

Combine/average with orange (½ red + ½ yellow + 0 blue) again to get (5⁄16 red + 5⁄16 yellow + 6⁄16 blue).

So your final result has just a tiny excess of blue over red and yellow. You can see this in the blue tinge of your final Glowbe.

The way the Glowbes' bodies seem to be drawn is that the lowest of the three primary colours' values is subtracted from all the values -- that is, the grey (equal parts of red, yellow, and blue) is removed, and the body is drawn with whatever is left. In this case, that's just 1⁄16 blue, on the black, so it comes out as a very dark blue.

It isn't the way I'd do it, if I were writing the game. I think it would be better if the grey was left, so you'd see a medium bluish-grey. But that's a matter of taste.
