I don't have an answer, as such, but I'd really like one! I would just like to add a few details.
I heard of a case where a Kurdish prisoner was dressed all in red, placed in a red cell, etc. for 12 hours at a time and then given several hours in direct sunlight. This was repeated continuously.
I know that red light is used in combat, as it does not affect night-vision. Maybe red, therefore, increases photo-sensitivity. Something to do with rods and cones, maybe. I'd really like an answer from somebody who knows what they're talking about!
Red blood cells. They give red colour to your blood.
red blood cells are red and white blood cells are white
Most blood cells are red, because the red cells are the most numerous blood cells.
Haemoglobin
They are red, due to their iron content.
They are red due to presence of haemoglobin.
Because it contains no red blood cells.
haemoglobin
hey them skiny colour is white only..but blood cells are red
Because it also contains red blood cells
Haemoglobin. That's what gives red blood cells their colour, too.
The Answer Is Circulatory System That Makes Blood Cells RED ! it is the heme part of the haemoglobin that gives blood cells their bright red colour.
