I would agree. Mata Hari and Amour are gorgeous blushes on medium skintone. For sure the colors may look intimidating when you look at it, but because NARS has so much pigment in their products, a little goes a long way.
Sephora Collection Pro Fan Brush #65
This is a great brush to apply blushes that have a lot of pigment. It picks up a light amount of product and deposits it nicely onto the skin. Just don't let NARs blush intimidate you when you first see it. They are all amazing!

This has a red, pink, and peach tone blushes with a highlighter. Great to wear individually and swirled in one. It comes with their award winning orgasm and matte shades of the others that are great to layer. Maybe this will help you make your decision
