I agree with everyone else about Trax, it's such an awkward color on me. I haven't found a great way to use it yet, I've tried it with more burgundy shades like sketch (I looked like I got punched in the eye, DON'T TRY IT!!!), and bronze colors, but it just doesn't look right.
I love Tempting, it's a pretty shimmery golden bronze color, perfect for Summer looks IMO. My trick to making lustres work for me is to put the color on with a smaller pencil brush, then blend with a fluffier brush. That way, the shimmer doesn't get everywhere when you first apply it.
