Actively removed?

It seams like this property is actively removed, any reason for that? https://query.wikidata.org/#SELECT%20%3Fitem%20%3Fcolor%20%7B%0A%20%20%3Fitem%20wdt%3AP2827%20%3Fcolor%0A%7D --Abbe98 (talk) 00:20, 10 July 2016 (UTC)

I think no attempt had been made to use this.

Okey, I have been prototyping a flower color tool, so had to check... --Abbe98 (talk) 07:41, 11 July 2016 (UTC)

The creation discussion was a bit too long, so we forgot to make use of it once it was created. I guess, it's all the better for you. Looking forward to see your tool in action.
--- Jura 07:44, 11 July 2016 (UTC)

@Abbe98 I added a wikidata game for "Flower Color" here: https://tools.wmflabs.org/wikidata-game/distributed/#game=30 Of course it has a couple of limitations. Most notably the fixed selection of colors and that it is only possible to add one at a time. I'm interested in your feedback and in what kind of tool you have prototyped.--- Iimog 08:51, 27 January 2017 (UTC)

Iimog, without good sources these additions are worthless. I reverted two of your addition allready. --Succu (talk) 09:45, 27 January 2017 (UTC)

Looks like your source is TraitBank (flower color) which in turn is heavily based on USDAs PLANTS Characteristics. There flower color is defined as the „predominant color of the flowers“. --Succu (talk) 17:14, 28 January 2017 (UTC)

Succu, thanks for the feedback. However, I don't agree that those additions are worthless without good sources. My assumption was that the flower color of many plants can be easily derived by anyone from existing images in wikidata and wikipedia articles. Many articles contain sections describing the plant including the color of the flower for example Monarda didyma contains "It has ragged, bright red tubular flowers 3–4 cm long, [...]". I think it would be very beneficial to have this information available in a structured, machine readable way. Therefore I built the wikidata game to make it easy for everybody to add those values. In fact I used the colors used in TraitBank as a preliminary list of possible colors in the game. As said this game has still some limitations. Nevertheless I consider the additions made by playing the game as valuable. As those additions do not have a source associated it is still easily possible to filter those entries out in a SPARQL query. Please let me know if you do not agree. --Iimog 09:55, 01 February 2017 (UTC)

Iimog, major Wikipedias criticize Wikidata for the lack of reliable sources and I agree. Guessing flower color (P2827) from pictures of uncertain quality (and origin) is banned by Wikipedia:No original research (Q4656524). --Succu (talk) 20:07, 3 February 2017 (UTC)

Succu, thanks for the further explanation. While I still think that more data of mixed quality can be beneficial I understand that in many cases less data of high quality is preferable. Therefore I deactivated the API action in the flower color game so that no more entries are added. Thanks again for your valuable feedback. Iimog (talk) 09:35, 6 February 2017 (UTC)
