Foundation help!

I have extremely pale skin and I'm also very cool toned to boot (I have the ginger gene to thank for that). I have never been able to find a foundation shade that matches me.. Ever. I've gone to multiple beauty boutiques and stores and nothing. I used makeup forevers ultra HD foundation in shade Y205 and I liked it but still too warm. I currently use covergirls outlast stay fabulous foundation in shade 905 which is the closest I've been able to find but still too orange. I also have oily skin but need full coverage because I have a tonne of acne scarring.
