Is there any difference between the Joolz Day Earth, Studio, Quadro, Sense and Tailor?

I mean technical differences between the prams? I can't find a comparison chart thingy anywhere!
TIA :)

It's just the colours

Thank you! That's what we thought, but then couldn't figure out why they'd given them such different descriptions (without actually mentioning any technical differences). :)
