Giorgio Armani No. 06 is a very warm-toned, dark coral with a luminous finish. It is a permanent highlighter that retails for $62.00 and contains 1 oz.
Giorgio Armani No. 06 Fluid Sheer ($59.00 for 1.0 fl. oz.) is a deep, vibrant coral-red with gold micro-shimmer. In the bottle, it looks like a softer coral, but one pump, and it might be a bit of a surprise. It can be as intense as you want it to be, so when it's applied as a sheer layer, it takes on a coral stain with faint gold shimmer, but it's not as opaque or as vibrant. MAC Simmer is pinker, but when applied sheer, it's hard to tell the difference. Tom Ford Flush is lighter, but again, applied sheer, the differences are minimized. See comparison swatches.
