MM capsule colors?

[cmb]

Hi all,

Is there a pattern or significance to the differently-colored boxes and seals used by Murray McDavid in the 1990s? I recently acquired a 12yo Leapfrog (bottled April 1999) that did not come with a box. I'd like to get a box for it (for aesthetic purposes), but I'm not sure if I should be looking for the orange one (which I've seen in many photos), as the foil seal on my bottle is gold-colored, not orange.
