Feature summary
Wikidata has datatypes for numbers, dates, and a number of other things. However it does not have a datatype and proper support for stuffs that are popping all over the place, like, here, colors.
Use case(s) :
The Wikidata property P465 https://www.wikidata.org/wiki/Property:P465 has 10430 use at the time of writing. It’s a property that stores a HTML coded color as an hexadecimal triple. It’s a popular and widely used color format, although of course not universal.
Benefits :
It would allow the color to be shown in the Wikidata user interface without ugly hacks, allow a proper support of colors in the query service visualization for example.
