Have a close look at the teaser photos, I think the stripe concept is a red herring and the colours to the right are the basis of each kit. The colours to the left look Photoshopped to darken the shade and provide contrast.

On the home kit, the colour change isn't symmetrical with the fabric and on the gold kit it just looks wrong. That is the kit that got me thinking.

I could be wrong but think it still could be solid colours.
