The best themes are the minimal white ones, they allow for more and easier customization. You can go for any second color you like without taking other elements in account. Changing other details like content width, etc. is more painless than with a non-minimal design.
Here you will find the top best white free and premium minimal themes.
Free minimalist themes
Manifest
A wonderful minimal design and layout that can easily be customized. This theme lends itself very well to use beautiful typography using @font-face which will give your website an unique brand even though using a free theme.
Modern
When I see this theme the word “delicate” comes to mind. The gray tones and the small type really gives this theme the minimalist look. Except for the logo there are no “hard” colors or elements that distract from the whole. A great theme for short to mid length content.
Modern Clix
A free theme that should be premium, that’s the only thing I can say about Modern Clix. With features like: grids, elastic design and standards compliant, heck it validates XHTML strict. This one is worth having in your WordPress theme folder.
Grid Focus
The theme that made Grid designs popular and mainstream. It inspired many other themes out there and is still a classic since being released a few years ago. Grids designs are still popular and if you have difficulty creating your own then Grid Focus is the way to go.

Premium Minimalist themes
Here is a list of the best premium minimalist themes. While there are some great free ones you get more when paying, think about an extensive theme admin to adjust everything from within WordPress admin, support from the makers of the theme and regular updates. Great for people who don’t have time or expertise to customize everything manually.
