Used as a term of endearment, sweetheart can describe someone you love or (in the South) anyone who crosses your path. Perhaps it is not love but the sweetness in the heart to find some good in everyone. If red is love then pink must be sweetheart.
A semi-solid colorway with shades of pink. Some have occasional spots of red and tiny speckles of blue.
Shown on Gluttony Worsted.
