I love Rimmel London Lasting Finish Lipstick in Airy Fairy. It is a pinky-nude and is only a few bucks!

I like the Milani HD Advanced Lip Color line. They're about $7 and they are great. There's a slight sheerness to it, but it works great with your lips and makes them soft. You might like Romantic Rose or Classy Nude. I have Classy Nude and I love it. It's not a totally opaque nude, but the sheerness works with your natural lip color and it makes it a pinkish beige like you are seeking. 

I have been wearing the CoverGirl NatureLuxe Gloss Balm this summer and absolutely love it. They have a variety of colors (pinky-beige is likely). It ran me about $8. You can read my review about the product here.  Good luck!
