As a Wikimedia Commons user I want to be able to search images by colour/size/format.
- Images by colour -> CirrusSearch, new Index
- Images by size and format -> CirrusSearch, new Index. Covered by T144447: [Story] Expose image meta-data to the SearchEngine
- In the long-run possible via Commons:Structured data
Needs to be further discussed with: WMF/Multimedia Team
This is part of the Top 20 wishes of the German community
