It's all personal preference, just as the clothing we each choose to wear.
As far as color, only you can make that decision.
Here is a picture of Athena
Here is a photo of Techo's Santorini. Not a very popular paver. But I think it turned out beautiful, myself, the home owners, and many of their friends love it. Closer to the $5/ Sf price. Depending on the square footage (over 2000 SF), you may possibly get it for less.
