What Fake Blood Should be used? -Research

Blood

For our film the causal agent is death, the death of the person in yellow. With their body bleeding all around the bathroom floor due to the multiple clean puncture wounds in his chest. (Discussed earlier in What Type of Knife Should Our Film Use- Planning.) With this in mind, what type of bleeding will be done here? 

Locational Based Injuries:

The injuries are in the chest area. This area being where the heart is located has plethora of veins and arteries according to the picture below:

A Picture of Veins and Arteries

With the picture in consideration there is plenty of blood to go around, and each color when damaged has a different bleeding type. The blue veins and the red arteries when damaged cause different reaction to blood being produced as seen in the image.

Different Types of Bleeding due to what was damaged

With the blood types being opposites, this will be interesting to do but allows me to widen and different blood splatter in the murder scene. Especially with the arteries getting damaged; blood will be blasting out wards getting all over the wall.

What Type of Fake blood Should I Make?

For fake blood we need dark blood closer and slowly flowing near the body. While the Arteries that are injured is lighter and further from the body. In this section how will we make this blood that matches. Using this video ---->

Looking at this video, the blood I need to make is going to use cornstarch as the blood thickener, and I have plenty at home. I will have to make 2 batches: with one having more blue food dye and the other with more yellow to get the difference in color or brightness.

Take Away:

For this film, based on the body's injuries and location, the blood will just be everywhere. With the need for two different color should not be too bad but, will add extra problems (like mixing it up) to the future. This was an effective post for me to gain understanding of how the environment should look at the murder which will be discussed in the planning post.
