Yes, in the time it takes you to formulate an applique plan, you could have ripped all that pink out and replaced it with yellow. If you don't like it, you don't like it. Nothing we say will change that ;-). It's very easy to fix...trust me, I did something similar recently. I know how painful undoing things can be, but in the long run you'll be happier for it.
Here's how to do it without having to do inlaid seams:
On the white strips joined with the pink, seam rip about a half inch past the pink, which will free two sides of the pink, plus allow extra for re-sewing seams without having to do set-ins. Then seam rip the remaining pink seam off. Sew the yellow square onto the seam where you've just seam ripped the pink, and then re-attach the white sides. This is all square work, so shouldn't stretch the blocks. If it does, though, do a little trimming up
Do you hear my experience talking? ;-).
Good luck.
