I'm NC35 and probably look even worse in pale pale colors (pinks/beiges/nudes) lol - I'm so picky with nude colors but I find the following works:
I hope that you don't mind some recs from brands other than MAC:
MAC:
Pinky-beige (but definitely not pale): hug me l/s
Viva glam V l/g - great with hug me and VERY versatile YLBB shade
Love nectar - great subtle peachy pink - definitely not pale, but just enough color to still be subtle with smokey looks
Underplay - I know this one is a warm peachy-caramel-nude, but give it a try - it has more pigment than freckletone (which unfortunately made me look like the living dead, despite being so pretty in the tube) - Love nectar looks fab on top of underplay, and it downplays the warmer caramel tones in underplay l/s
Dior:
Try any of the new dior addict ultra-nudes - they have just enough pigment, but are still very neutral/subtle
If you are looking for a very sheer wash of soft color (pink or beigey), browse thru the dior addict ultra shine line - they have the best glossy texture and look and are so comfortable to wear - they apply very sheer but you can build the color up no problem - therefore it's versatile (sheer coat with a hint of color for dramatic eyes, or build up the color for day time eyes)
Good luck!
