retopoogy error

why do i get these kind of error ? texture sold doesn’t cover those faces



judging by the light colored patch, some of your normals are inverted. select all and ctrl N ( recalculate normals outside ), or select just the faces that are affected and ‘flip normals’ from the mesh menu or the tool shelf.

NOt really, i have tried that but didnot match color of the texture solid. once i foud the solution but then i forgot. also tried to select all and unwrap but didnt wokr
