Talk:ListOfColours

But does it render?

I disagree with this extensive list of colours. I think we don't need to impose this list on the data consumers when they could simply use the hexadecimal color. The colour name (instead of an hexadecimal colour) exists so the OSM mapper can easily describe a colour without needing to lookup the hexadecimal colour every time, however I think it's highly unlikely that an OSM Mapper would remember the colour names of such an extensive list (i.e. he would have to lookup anyway). --Jgpacker (talk) 14:27, 10 May 2015 (UTC)

Some of the colours are already extensively used, if you look at https://taginfo.openstreetmap.org/keys/roof%3Acolour#values and https://taginfo.openstreetmap.org/keys/building%3Acolour#values

although as a mapper, i would personally prefer the hexadecimal notation, which i can pick in GIMP or other tools. You can find way more extensive lists in wikipedia. I only found Key:colour so far, which is very limited.

Ok, but isn't it better to just link an external page with such a list? This way we could say something like: "Some renderers may also support the list of extended colour keywords from the CSS Standard". --Jgpacker (talk) 15:25, 10 May 2015 (UTC)

Since I'm not convinced this page should exist, I'm redirecting it to Key:colour after following my own suggestion above. --Jgpacker (talk) 02:05, 28 May 2015 (UTC)

Interesting conclusion. All right then. I rephrased the paragraph a bit and fixed the link. --Aschilli (talk) 12:39, 28 May 2015 (UTC)

Thanks! --Jgpacker (talk) 12:40, 28 May 2015 (UTC)

Where does this list come from?

As one of the data consumers this list would be very relevant for, I'm surprised about it suddenly "falling from the sky" - that's my impression at least. Where is this list sourced from, and what advantages does it have over other lists? I'm also concerned that the colors seem a bit too bright to be used on buildings and such. --Tordanik 21:44, 10 May 2015 (UTC)

Many such lists exist, such as http://en.wikipedia.org/wiki/X11_color_names, http://www.color-hex.com/color-names.html, http://en.wikipedia.org/wiki/List_of_Crayola_crayon_colors, http://www.html-color-names.com/color-chart.php, http://en.wikipedia.org/wiki/Web_colors

the definitions are all the same across these sources

Having a list in this wiki could help reduce the number of possible values in OSM. It could be extended as needed. As I said, they are already used. I dont find them very suitable for 3D mapping either. I must find the exact source of this list, since its some time ago since i copied it. Must be CSS/HTML colors. Reference to a good W3C page could be also used if you none of you agrees. --Aschilli (talk) 06:40, 11 May 2015 (UTC)

The reason I discovered this list was because it was added to various 3D-related pages (building:colour=*, roof:colour=* etc.), so I would like to have things clarified in that problem space in particular. As for the various lists, here's another (albeit less "serious") one: http://blog.xkcd.com/2010/05/03/color-survey-results/ --Tordanik 12:48, 11 May 2015 (UTC)

The reason I bother with color names is that mappers start using them in really peculiar ways, perhaps totally oblivious that there is more than the primary colors.

I see purple, blue, pink, green, yellow...... seriously?! It looks more like Candy Crush Saga, but its not the fault of the renderers, since colors are precisely defined by the sources I provided. Apparently mappers must be made aware that they can choose from a larger set of values. They tag some "bluish looking building" with colour blue, which is #0000FF, and roofs with shingles as red, which is #FF0000...some poisonous sea snails looks like this...... --Aschilli (talk) 15:38, 11 May 2015 (UTC)
