Keynote Hub (http://www.keynotehub.com), a new Keynote theme store, is offering three new themes for Keynote. Keynote is the presentation creation component of Apple’s US$79 iWork suite.

The three new themes — Brownstone, Esquire, and Simplicity — are focused on the fundamentals of color, typography, and layout, according to the folks at Keynote Hub. Brownstone is inspired “by the timeless elegance of New York’s brownstones.” Esquire is “bold, powerful, and a bit whimsical.” Simplicity is a minimalist theme, “with a simple but powerful style.”

All three themes are available in 1024×768 screen resolution, come with over 20 master slides, and are priced at US$19 each.
