Thumbs color 18.2 iPhone 14

I changed the color of the emoji on iPhone 14 Pro Max accidentally (I didn’t mean to) iOS 18.2 I tried previous answers to revert it back to original color (yellow) it won’t change back. Did the double tap thing no color bar, only put thumbs on post. Is it diff for 18.2? Inquiring mind needs to know m.

TIA gang!
