I'd love cherry-red curtains in our big bay window, but the room faces south (well, a bit east of South) so would they fade in no time? I have this idea that red fades faster than other colours, but I don't know whether that's actually true or not. Does the fabric make a difference? I could cede velvet if some other red fabric fades less.
Even if they did fade, couldn't it just look nicely lived-in and not horrible?! Hmm, not sure I'm going to win this argument...
