What does "no accounting for tastes, there's" mean?

Individual likes and dislikes defy explanation, as in They painted their house purple—there's really no accounting for tastes. This expression, first put as no disputing about tastes, dates from the mid-1600s; the present wording was first recorded in 1794. A mid-20th-century synonym that originated in the American South is different strokes for different folks. For a far older synonym, see one man's meat.
