Planet Logo color variations

Allthough I liked the initial color scheme of the "Logo"...

(Yes I know, it's not really a traditional logo.... it is very detailed, doesn't work well in grayscale, works even worse in black/white.... also it doesn't have those horrible graphic logo design rubishes on it)

Anyways.. I really liked it but here are some other color scemes. My personal favourites are the 1st, 6th and 8th.
