A little bit of wet look can be displayed. But cannot identify that is blood without examine.
depends how much blood
no but small spot
Why is there blood on it?
depends on the fabric, how much blood, &if it is fresh blood or dried blood.
I have a bad primonition on this kind of question.
Not really.
Very lil noticeable,it will just look like a Un dried up water stain
no its not
It would depend on the fabric It would most likely be somewhat noticeable in day light but you wouldn't be able to see it at night
