Color correction advice

Hello!

I have recently discovered i have light olive skin with Neutral undertones, which explains why most of my foundation didn't look lighter or darker but just... Off.

And as you would expect most of what i bought were too orange or too pink/peachy.

I was advised to use blue color corrector (or potentially purple ,apparently) for the orange ones and orangy color correctors for the peachy leaning ones.

And so, i whished to ask, what would you suggest to neutralize these foundations, am i on the good road by using blue/purple or orange?

And most importantly, i can't find a blue color corrector for the life of me, so if anyone could suggest individual color correctors, or even better, a palette that's good quality i can use, that's budget friendly if possible. But im still open to any suggestions.

If possible a brand available in Europe 🥲 france if possible.

Thanks if you took the time to read this 🙏 a girl just wanna use the foundations she waisted money on
