The Blommor01 theme is designed by Masumi Hirose.
It's a two column blog theme with a lot of transparency. The main colours are black and red with a bit of yellow. The demo site show a blue colour variation of the theme.
Its base is the hiroshigeblue theme. Pure CSS layout. Standards-compliant XHTML 1.0 Strict and CSS. Do not work so well as a admin theme but with Drupal 5 and later it's easy to set a administration theme. The transparency doesn't work in Internet Explorer 6, it has no support for transparent PNGs or modern CSS.
