The color we really don't want is orange, purple is just not our favorite, but it is ok in your logos. I think these are great, maybe try different font. Also the Jupiter part is slightly more important in our name so you can try to place emphasis a little bit on that part.
Also please keep in mind that we're Projekt with "K", thanks.
Thanks for the look and feedback and I'm very sorry about the spelling error - I'll certainly correct that and follow up on your requests soon. Regards, Steve.
