As far as I know, this is now permanent. It’s pigmented like hell and If you put too much on, there’s no way to sheer/blend it out. The colour is very pretty, but if you use too much (or have some natural redness in your face), you could end up looking like you have fever.
Chanel Rouge Joues Contraste / Blush ($43.00 for 0.14 oz.) is a darkened scarlet red with a satin sheen. It’s very, very intense. You’ll need a light hand with this particular blush, because it is easy to go overboard. When you use a light hand, though, it does tone down to more of a medium-dark pink–it doesn’t look red–which looks like a soft flush.
