There are no "true rose" anemones. I know sometimes they get advertised that way, but roses just come in a very large variety of colors. There are some that are deep red, there are some that are cheetos orange, copper w/yellow tips, more pink than red, brick red, red half way down, red all the way to the disk, some that look red in one person's tank and brown in another. Any and all can have tan, red or purple bases. Most of them will not look the same after a year in your tank as they did when you bought them.
Some really nice ones come from Bali, so do some pretty pathetic ones. I saw a couple tanks full of "true roses" from Bali a couple weeks ago and they looked exactly like the greenish base, pale pink tip (soon to be brown) rose anemones that flooded the market a few years back.
I know the color you are looking for. The dark tentacle base is more a function of the anemone's condition that anything else. I have seen anemones that come in like that lose that dark base in a week or so in a retailer's tank.
The color you are looking for is very hard to come by and usually fetches a pretty hefty price ($150 - $300) in online stores and even LFSs.
Your best bet is to find someone local who has one that splits. I know the SoCal Reefers forum here allows "want to buy" posts. I don't know if the other local club forums do, but that would be your best chance to find what you want. If nothing else do a "Let me see your Rose Anemones" post in the Orlando area forum and then privately contact the person with the one you like best.
