50 free Orange trivia questions with answers — food & drink quiz, new questions added Aug 2026.
This orange trivia quiz starts with the fruit (a hybrid of mandarin and pomelo first mentioned in Chinese writing in 314 BC), moves to the colour that took its name from it, and then follows the word wherever it went: the House of Orange and the Dutch national colour, the Roman city in Provence, the Orange Free State and Orange River, Agent Orange, the Orange Bowl and A Clockwork Orange. Along the way you will find out where the navel orange was born, why Louis XIV confiscated a thousand trees, how the letter n fell off the front of the word, why Dutch carrots are orange, what makes a blood orange bleed, and which mineral gave ancient painters their orange before the fruit had reached Europe. Easy questions sit beside genuinely hard ones so a family or a pub team can play the same set. Every answer was checked against Wikipedia's articles on the fruit, the colour and the related people and places, and each question quotes the sentence that supports it.
