Q.Red Colored Clover In My Lwn
The cover leaves are red and eventually there’s a small yellow flower upon maturing. I mistakenly thought it was “red clover”, but apparently that has a yellow flower and is used as a cover crop. Can you identify this pervasive weed in my lawn and help with an effective herbicide? Thank ypu.

It is likely creeping wood sorrel. You may need to use pre and post emergent herbicides to combat it. These articles should help with control:
