The big news out of the Ubuntu world this month is the radically refurbished look introduced to accompany Lucid when it's released in April, replacing the orange-brown "Human: theme that Ubuntu users have known and loved - or not - since 2004.  Here's a look at the new face of Ubuntu, with an attempt at abstract thoughts related to it.

Canonical is updating Ubuntu's look and feel with a new style that departs from the popular Linux distribution's traditional brown theming. The new theme, which was announced yesterday as part of an initiative to overhaul Ubuntu's branding and visual identity, will be used in the upcoming Ubuntu 10.04 release, codenamed Lucid Lynx.

Ubuntu users were promised a radical new desktop theme with Ubuntu 8.04 and then that ended up getting postponed to the upcoming 8.10 release (a.k.a. the Intrepid Ibex). There was a new brown theme that had appeared early on in Intrepid but many users were dissatisfied with this work and Canonical ended up reverting the theme to that of Ubuntu 8.04 and earlier.

The completely new theme for Ubuntu 8.04 has been deferred to the following release. The original plan was to have a fresh theme for every long-term-support release, starting with Ubuntu 8.04 Hardy Heron. Now it has been decided to put off the redesign until Ubuntu 8.10.

Sorbet is another proposed theme for Ubuntu 10.04 Lucid. Ubuntu derived theme with subtle gradients and lighter colors based on a loose interpretation of the new look of Ubuntu\'s Single Sign On. Metacity buttons based on the phenomenal Homosapien theme

Ubuntu's goal to to present the user with a welcoming desktop environment. Although the current theme is a step in that direction, the bright colors and overly bright theme. Warmth aims to be a softer, more blended theme, while still remaining within the ubuntu color scheme.

There have been promises of an overhaul to Ubuntu's default theme for quite some time. Ubuntu 9.10, set to be released at the end of this month, will begin delivering on those promises.  Below, we take a look at the new system theme and artwork that will debut in Karmic Koala.
