I haven’t tried these themes, but they were so pretty, I just had to share them with you.
If you are looking for an unusual theme for your WordPress site, I would like to offer the following group of one dark theme and two white ones.
Royale – this is simply beautiful as a dark, rich, textured site. Leaning toward a gothic/dark victorian feel, I can imagine many incarnations of this basic black site.
Zen – (from designer, MiloIIIIVII) This sleek Asian themed, 3-column orange site is both simple and striking. It’s widget read (plugins required) and offers a fixed width format.
Reflex 1.5 – (from designer, MiloIIIIVII) Ah, for the love of purple! This theme incorporates one of my favorite tones of one of my favorite colors into a high-impact them with a 3-column fluid layout. Although one version is on the WP Theme Viewer, the most up-to-date version is on the designer’s Insomnia site. (And you can view other themes here too!) (Update 4/2011) – I have removed all the links to this theme since the site is broken.)
