Sure, blood doesn't need to be in a story for it to be creepy, but if you want to add it in to enhance your story, then you should do it right.

A great example of the color of blood used to enhance a story is Del Toro's work. I know that his is a visual art but I think the same can be applied to the written arts. In some of his works, you will notice that everything is bland, bleached of color. But the blood is bright with a thick red, making it stand out. That enhances the story Del Toro is trying to tell.

I believe similar techniques can be used in literature too.
