Women Of Color

I know this app is for periods but I need help with some makeup and don't know where to ask & this app has some genuine, real & nice people so I thought I'd ask here. I am mixed of black and white, I'm "lightskin" I guess you could say but is there any woc who have yellow undertones who knows a good foundation bc every foundation I get has red undertones & I end up looking a mess! No high end makeup please, just drugstore! I just need a little bit of help, thank you :)
