Categories
edit- 1. element to cat
- 2. cat to elements
- 3. distinguish cat areas (border in pt)
- 4. pleasant view
- not
- x1. association (x 'red=alkaline reactive')
- x2. disrupt text (?)
Requirements, to solve
edit- 9+1 colors (2018): Number of categories: 9 identified, + 1 "unknown chemical properties" i.e., category can not be established
- ? Could it become 10+1? (it was before 2018, ie set 2013)
- border illustration:
- Possible diagonal mix for border elements. Colors should be distinct wrt this. (new)
- distinct classes, not fluid
- would confuse? Doubted classes (say metalloids) could be noted differently. (hatching)
- Legend
- Recognisability in-table <--> legend below connection
- Do not use associations (not "metals associate with silvergrey"; not "alkalis burn easily so are red")
- Do other sets (blocks, ...) are not considered simultaneously (do not appear in the same table)
- Advise a sequence in the periods (left-to-right) OR require circular consitency (NG-AM)
- Advise/check sequence for variant PTs (Left Step, ...)
- Contrast check wrt background (white or near-white)
- Future: allow mixed colors (diagonally mixed?). color requirements?
- Fontcolors used (css-style attribute:color):
- 1. black and wikilink-blue (local link, visited/notvisited):
- A
black→#000000 - A #0645AD --bluelink
- A #0B0080 -- bluelink, visited (help)
Fontcolors: State of Matter, wl
edit- State of Matter fontcolor used:
- A
Solid→#000000 - A
Liquid→#000000 - A
Gas→#000000 - A
Unknown phase→#000000
- IOW, black is used twice (meaning 'solid')
- A
wikilink→#0645ad

Recognition and distinction
edit"Recognition and distinction" are requirements for legend colors to check that the reader is able to recognise a set (category), to distinguish different sets, to find a map color in the legend and —reverse— find a legend color on the map.
- The reader should be able to discern color borders (where does a category end?, where does it meet an other category?), and also recognise (group) same-color disjoint areas.
- ① Find element-color or area-color in the legend
- ② Identify single-color set (can be disjoint), and distinguish different sets at border.
- ③ Find the area (elements) from a color in the legend
- When checking for color blindness accessibility, these requirements are of huge influence.
- See also: "info not by colors alone".
- On second thought, the #2 can be split: 2a. see a group/map area, even when disjointed; and 2b. see distinction from different map color area. -DePiep (talk) 23:17, 4 January 2021 (UTC)
