CO is designed as an ergonomic replacement for the default Windows Classic theme. It was designed with long-term use and compatibility in mind.


- 5 colours: Alpha, Blue, DeviantART, Green and Dusk
- Normal & Compact start panel versions
- Classic and Coloured taskbar versions
- Matching wallpapers and shellstyles
- Yz Dock by Manyk (no Dusk)

- new font choices:

Normal: Tahoma 8
Large: Arial 8
XLarge: Frutiger Linotype 8

The icons in the screenshot are Marvilla's Pastel set ([link]).

The GANT set goes very well with the new Dusk version!

Please refer to the readme (included in zip) for full theme information (and update history).

Hope you enjoy the theme, comments would be appreciated :¬)

Thanks a lot for this skin. It feels like a natural update of the old watercolor theme I've used so much for years, but which has begun to look rather tired (or at least I'm tired of it.) I really prefer themes that look like they could be factory themes for Windows, if only Microsoft had any taste, rather than all these weird skins that look neat for five minutes but wear out their welcome fast.

Excellent work!

Thanks for the superb themes! The only one I am missing is red look with Opus themes, the way red GUI Relax is made.

what is the font name used to write "Codename: Opus" in the screen shot? Is it possible for me get a copy of that font?

I've had to switch to Windows at work recently (was previously using MacOS and Linux) and it's very hard to find a theme for it which looks good while retaining usability. So far this is the closest I've found to anything I want to use long-term. Thanks!
