An edge turned pinkish but it's not seam after putting subdivision surface modifier I am making the Blender Guru donuts. I noticed this edge of this reddish color after putting subdivision surface on the donuts icing. It's not seam cause I can't remove it with U -&gt; Clear seam.

What is it and how do I remove it?
I guess it's the Crease, select this edge loop, open the N panel &gt; Item &gt; Edge Data and bring back the Crease to zero, or select, ShiftE and drag. It is used to sharp angles.
