helping me find my undertone

so i have a light medium skin tone and i kinda believe i have a strong yellow undertone (due to the fact that i look yellow and when people kind of really notice my skin tone they notice how yelpow i am) anyways i wanna cofirm because i know theres a different between skintone and undertone.

so i tried looking it up and i looked at my veins and tried the white paper test and the gold and silver test. i kept getting different results and different answers or i was never sure cause i have poor judgment. the only one i was sure about is that i look better in gold than in silver so theres that.

also i used to wear the maybelline fit me foundation in the shade 120 but it was way too light and it also appeared too pink on me. i went a shade darker to 125 and it was still late and it appeared pinker than 120.

im now currently using (not really using but recently bought) the wet n wild foundation in the shade 368c golden beige. i know i dont have a golden undertone but that was the best i could pick closest to my shade in a hurry. the shade is a little too dark but its kind of close to my skin tone. however it makes my skin look orange (not very noticeable but i notice it lol).

anyways i still believe i have a yellow undertone (maybe some of you can figure out whether its true or not based on the information ive given you) but im still having trouble finding my shade (i only use drugstore cause its what i can afford). if you do think i have a yellow undertone what are some drugstire foundation youd recommend? because from what ive seen the fit me maybelline foundations have mostly pink undertones.

first one is with flash in front of my window, second is with just na

tural lighting, third is also with natural lighting.

this one is some messy swatches of the foundations i mentioned i use. to be honest they dont look the same as they did irl.... and also my skintone on my hand is darker than my face...
