The fruit named the colour
English had the fruit before it had the colour. The Online Etymology Dictionary dates the colour word to the 1510s — “a reddish-yellow color like that of a ripe orange” — and notes that Middle English called similar colours citrine or saffron. The American Heritage Dictionary likewise puts the colour use in the 16th century.
So the popular shortcut “the colour is named after the fruit” is directionally right in the two dictionaries that date it: the Online Etymology Dictionary and the American Heritage Dictionary each put a colour use later than a fruit use, while Merriam-Webster gives no date for the colour sense. The dated records still differ — late 14th century for the fruit in Etymonline, around 1400 for the first orenge spelling in AHD's account, and Merriam-Webster's 1532 and 1542 for two other named senses — so no single “first orange” date is claimed here.
