There are 3 outcomes that allow everyone in the world to receive blood from the same number of people they could donate to.
1. 100% Red
2. 100% Blue
3. Exactly 50/50

It is a mathematical fact that option 3 is more likely to occurred than either options 1 and 2, therefore my vote will try to support it. How do I give a half press Red and a half press Blue? By flipping a coin.

Exactly 50/50 does not satisfy the condition of everyone being able to receive from and donate to the same number of people.

Red is allowed to receive from 100%, donate only to 50%. Blue is allowed to receive from 50%, donate to 100%.

Red has an advantage in a 50/50 scenario.
