Since your blood is on white, this is behaving normally. Black would be transparent with plus, since x+0=x. Either invert like you're doing, and use some color correction to make the cyan blood red again, or use some keying and shuffling to make a mask for a red constant, or reshoot your element on black for it to work as a plus. What you probably really want to do is use multiply instead of plus anyway.
