plural of adjective orange
i was totally stumped on this one: Elles peuvent être rouges, orange, blanches, jaunes et bleues. first, i could not differentiate between elle and elles so did not pluralize any of the colours. That aside, why is orange not pluralized with an "s". Is this an exception?
Indeed, certain adjectives for colors do not change.
Yes it is an exception because orange is taken from the actual fruit so you're not supposed to conjugate it ever. The same with if you said 'Les papiers(papers) rouge cerise' Since we're saying cherry red we don't conjugate. it's the same with other double-barrel colour names like chocolate brown etc.
Indeed this is a tricky part, with several exceptions, that natives do not always get right.
For french speakers, a few english words are tricky as well: police (you are police ?), pants, fish (I ate several fish), hair (your hair is a lovely brown. I found three hairs in the shower), and so on.
