Do you put color corrector on before or after makeup?

I'm curious, in the realm of beauty routines and particularly when it comes to applying makeup, what's the recommended order for using a color corrector? Do you apply it before your base makeup as a way to even out skin tone and address any discoloration, or do you reserve it for after your foundation has been applied as a means to touch up and refine your look? The answer, I believe, could significantly impact the overall outcome of one's makeup application and the final appearance of their skin.
