OP, I have long awaited the perfect shade of rouge from H. It is to be my one red bag, and from H at that. For these reasons, I want to be mindful of cost/utility - it has to be just right.
For me RC is pretty but very bright, RT is too orangey as the name suggests, Peony and Duchess too pale, Rubis has a pink undertone I dislike. I love seeing Rouge H and thought it may be the one, but prefer earlier iterations over later(which has a distinct brown undertone) plus it is very hard to come by. Bordeaux is a beautiful deep, deep red(almost presents as cherry red in shoes) but I haven't seen a bag done in this shade. Rouge garance is nice, I just wish H could blend it with Rouge H and just maybe, finally, a perfect red hue will be a reality.
Then, quite providentially, my perfect red came. Rouge Grenat in clemence w/ghw is very pretty. Quite irresistible, as I had not considered the color until SA suggested it. Many of them concur, Grenat is as close to the original Rouge H as reds have come. This red has none of my reservations about the other reds I mentioned above. I think it is elegant, outstanding as a red yet subtle and muted just so it isn't loud.
