Welcome

Periodic Table Graphics (PTG) is a taskforce of Wikipedia:WikiProject Elements (talk).
The taskforce aims to improve graphic and presentational aspects of the periodic table. It follows and shows scientific content.

Scope edit

The graphics, not the scientific content.
By theme (topic), like categories, blocks, or by editorial form (like 18- or 32-column)

Goals edit

Goals of the taskforce are to improve graphic presentation of the periodic table. This includes

Present scientific information appropriately and usefully. Considering Wikipedia is an encyclopedia.
Apply WP:ACCESSABILITY ('A11Y') guidelines, aims and principles.
Improve explanations, descriptions etc.

Tasks, Active edit

State of Matter (SOM, Jan 2021)
  • Current 2020 SoM coloring (=use font colors) has issues.
As of 2021-01-23, an Emergency Edit has been made to make SoM-fontcolors into black all. W3C Contrast checking failed too often (5/18 existing combinations!)
A new presentation form (like icons not colors) is considered.
See Wikipedia talk:WikiProject Elements § Emergency edit: remove fontcoloring State-of-Matter, has wider discussion, interesting

Tasks, Future edit

Micro PT (MICRO)
  • Could be redesigned to be more useful (like using larger cells).
Also, as used in {{Infobox element}}, can be made more effective.
Crystals
In {{Periodic table (by crystal structure)}}
The legend setup could be better. Why not use iconic images instead of colors? -DePiep (talk) 23:53, 23 January 2021 (UTC)[reply]
Metalloid graduals
These four classes better have gradual colors (say, blue-to-yellow in 4 steps).

Tasks, Past edit

... – 2021-01
Category colors (CAT)
  • As of Jan 2021, this Taskforce PTG was buzy to find better category-colors.
Current live colorset is "2020" (as of 31 Dec 2020), see Wikipedia:WikiProject Elements/PTG/categories/2020 and {{Periodic table}}.
Moot as of Jan 17, 2021

Conventions edit

  • In PTG, hex color triplets are shown in lowercase: 3af8ee.
  • "Chemical categorisation" explicitly refers to the science. For example, the "2020 categorisation" scientifically re-introduced "Halogens" category. After this, the topic "Colors of categories" will follow.
  • Category names are not relevant. For example, former PTM Post-transition metals is in 2020: OM Other Metals. Does not effect color design.
Also, exact category memberlist not very important. Except maybe when checking for neigbours (bordering).
