With the 3.2.1 version, the old icons for both the applications and the documents have been changed to a new set (refresh). Main concept was the introduction of the orb and the removal of the colors that were used until then. Only the blue color had been kept to indicate an ODF file format. This change, introduced by the OOo team was rather astonishing and many users disagreed. With AOO 3.4.0, the old set of icons has been re-activated (except the main icon with the orb).
As the main problem with the new icons set (refresh) was the color, perhaps there is a solution somewhere between the old colored set and the new more modern look.
Some links:
Old set of icons: All MimeType Icons :: Applications, Documents & Templates of OpenOffice.org 3.0
.odt:
The color explanation: The Galaxy Icons:: MimeType Icons, Color Language.
The rebranding page: Visual Design, UI and Branding.
And the new ODF icons: The ODF Mime Type Icons. The page for the whole set is not available anymore (http://odftoolkit.org/ODF-Icons).
But they are still available on Wikipedia:
.odt:
, .ods:
, .odp: 
With some rationale: Unified ODF Icons - Specification.
Here is my proposal, roughly mixing the the new icons with the old colors:
.odt:
The .odt version is not that good since we don"t really see the blue color. But I'm not a designer, that's just to see if this kind of proposal gets some popularity or not.
But also some other proposal:
- Drew's icons in the topic: New Icons ... I don't like them:
- vea1083 icons (same topic as above):
For the record, the current rebranding page: Apache OpenOffice product and project name decision & next steps.
And the LibreOffice icons that looks not that bad: TDF wiki - Design/Whiteboards/LibreOffice Initial Icons
Additional links:
- Initial discussion on the ooo-dev mailing list
- Rework of the unified ODF icons by I-team (with an interesting proposal to reintroduce the colors as badges.
Any thoughts???
