Just colors doesn't me feel that it is rainbow
I wouldn't have said the point is to look exactly like a rainbow, the point is to create a striking image that works well with the product. It has the retro feel of the 80's consoles combined with a smarter, more up to date image. For me there's still something very stylish about it I can't quite describe...it's something to do with the dark greyish background... and the clean-cut, washed-out tones. It's both subtle and faded and clear, like levis or something.
However, although I know you're just exploring atm traylorpark, and I like the bouncy curly ribbon a lot, it reminds me of some sort of candy, I'm not really sure where you're going with the latest image. It looks a bit strange having a box and ribbon that are completely 2D, with zero perspective, suddenly have a lot of perspective, and the way it goes straight up out of the box, then bends and goes down again (up-right-down-perspective) doesn't really seem quite right to me. Maybe if the ribbon fell straight over the edge of the box and piled up in a heap? But then you loose the very striking straight lines and some of the association with the rainbow lines of retro consoles. However, something like this might work well for an animation, flying up straight out of the box and then falling in a heap or similar.
Just my opinion of course, I'm no expert, and I don't know if I've properly explained my thoughts! (And I do really like it all - plus it's not like I could do better!)

Aw yeah, I'm back on topic!
