It’s a subtle distinction, but “rose” is French for pink and “rosé” is French for pink-coloured. If we had the verb “to pink” in English (as they do in French) then we’d translate it as pinked.
Putting the é in is easy though, it’s just alt+e. It’s the è, à, ç and ù that get tricky, unless you’re using a French keyboard like I am 😉
