Color for correct PE logo?

[on:]

Hi,
I'm wondering which one is the correct Planet Express logo? Very often, it contains just a black rocket but on other scenes or products it has a light green rocket in the middle of the logo.
I tried to find out by watching the 2nd episode (on the moon). There is a very strange scene where the crew watches the commercial on TV. When the delivery boy hands out the package there, the package contains a black rocket in one scene and a light green one in the very next one on the same package! The space ship seems to have the green variant in most times.

Whaat do you think, what is the correct one?
(I'm thinking about buying a T-shirt with the logo but I don't want to wear the wrong one)

Green is the correct one I believe, the rocket must've been Black in that early episode, well, because it was an early episode. They were probably still testing things out, like how Zoidberg used to have teeth.

Although I think it could be both... Either way, green is used more than the black one.

I would just buy the PE T-shirt from Comedy Central; that seems pretty official to me.
