The ruling on the color of blood if it remains on the garment after washing it?

Question:
He says: Honorable Shaykh, may Allah preserve you. If blood is ritually impure, and the blood is washed from the garment, but some of the color remains, is it excused?

Answer:
If he is unable to remove it, it is excused. If he is unable to remove it, it is excused. But if it is possible to remove it, he must do so, because the remaining color is evidence that the blood remains.

Yes.
