Since my favorite, Blonde, has been discontinued I have been wanting something similar.
It was a toss between Rio or Lust and I ended up getting Lust.
The website states Lust as a pale pink with cranberry pearl.

It is highly shimmery and when blended creates a beautiful pink glow.
Here I am wearing it as a highlighter and it gives a nice pink glow. I am an NW15/20 for reference. 
In the above photo I compared MAC MSF in Blonde to Lust. Blonde is on top and is much lighter in color, more of a baby pink but still has the glow.
I am very pleased with Lust and will use it often as a blush, highlighter or eye shadow.
I may go back for Rio but I am reallllly loving Lust.
Rio is a bronze with pink pearl
I think that that maybe a closer match to Blonde as its on the cooler size. * Below if from MAC's website*

with high-frost metallic finish. Smoothes on: adds buffed-up highlights to
cheeks, or an overall ultra-deluxe polish to the face. A luxurious
