Cool Undertones

Just starting out with trying out makeup. I’m so excited but absolutely and utterly lost. I️ should have taken cosmetology in high school 🙊 I️ have purple veins which means cool undertones (yay google!) Does anyone have any recommendations on high end foundations for cool undertones? Like tarte, urban decay, etc etc? Or any tips? My 1 yr old doesn’t rly let me watch YouTube in peace
