I bit the bullet and swatched Topkapi but as its cloudy out the pictures are coming out crappy. MrsB's swatches are great at capturing the colour though!
Heres swatches of (L-R) Or blush, Rouge blush and RA Byzantin
I tried Rouge on my cheeks just now and all I have to say is make sure you use a very light hand! Its very bright even on my NC35ish skin! I wore the RA and I love the formula! This was something that I was very worried about (apart from the fact that its red) as RC's usually dry my lips out but this formula is great - not moisturising but not drying either
I had to tone it down by layering Girl On Board on top before I got out the house! I'm not ready to wear red out yet!
