With dehydration, the blood literally becomes thicker as blood cells and proteins become concentrated due to loss of the liquid fraction. When this occurs, it is difficult for blood to penetrate the tiny blood vessels called capillaries, which are present in every body structure.
The blood is darker due to the increased number of RBC's and High HCT.and a decreased blood plasma volume and osmolality.

Too simple:
Think of hemoglobin (red iron complex) as a pigment or dye.
If you put one drop of dye in a cup of water, it will be a lighter color than one drop of dye in a teaspoon of water.
By definition, you are dehydrated the hemoglobin dye is more concentrated and appears darker.

Because there is low water content in your blood, therefore it's thicker. And vice versa, if you had more water in your blood the thinner (and lighter/more deluted) it would be.

Bright red blood is oxygen rich right? There is oxygen in water right? I think that might be the connection to your delema.
