This depends upon the complexion of each individual. But based upon your pic, I'd recommend the polka dot pattern, #2. This would combine well with any of the other violet/ lavender patterns, perhaps #1.
Yes, absolutely. I used a colour wheel generated for my type and try to choose colours based on that, but with an eye to what would look good on the floor. Doesn't always work, sometimes what I end up with looks great but not on me, as I have to order the materials online and they aren't always what I think!
