Editing Orange (colour) (section)

===Orange natural objects===
The orange colour of [[carrot]]s, [[pumpkin]]s, [[sweet potato]]es, [[Orange (fruit)|oranges]], and many other fruits and vegetables comes from [[carotene]]s, a type of [[photosynthetic pigment]]. These pigments convert the light energy that the plants absorb from the sun into chemical energy for the plants' growth. The carotenes themselves take their name from the carrot.<ref>{{cite web|url=https://www.britannica.com/EBchecked/topic/96623/carotenoid|title=carotenoid|website=Encyclopædia Britannica|access-date=25 September 2014}}</ref> [[Autumn leaf color|Autumn leaves]] also get their orange colour from carotenes. When the weather turns cold and production of green [[chlorophyll]] stops, the orange colour remains.

Before the 18th century, carrots from Asia were usually purple, while those in Europe were either white or red. Dutch farmers bred a variety that was orange; according to some sources, as a tribute to the [[stadtholder]] of [[Holland]] and [[Zeeland]], [[William the Silent|William of Orange]].<ref>{{cite news|url=https://www.washingtonpost.com/blogs/wonkblog/post/carrots-are-orange-for-an-entirely-political-reason/2011/09/09/gIQAfayiFK_blog.html|title=Are carrots orange for political reasons?|newspaper=Washington Post|access-date=25 September 2014}}</ref> The long orange Dutch carrot, first described in 1721, is the ancestor of the orange horn carrot, one of the most common types found in supermarkets today. It takes its name from the town of [[Hoorn]], in the Netherlands.
