red blood is oxegenated; it has oxygen in it
blood blood is not oxygenated; it does not have oxygen in it
Arteries have red blood in them; they go to muscles so the muscles can use the oxygen, Veins have blue blood in them; they go back to the heart to go to the lungs to get oxygen
when you get cut, even in a vein, the blood is red because when the blood comes out it becomes oxygenated. Although, when an artery gets gut it is bright red, although when a vein gets cut it is dark red. JACOB PONTOW IS A BEAST

The difference between blue and red veins primarily relates to the oxygen content of the blood they carry. Red veins, or arteries, carry oxygen-rich blood from the heart to the body, giving them a bright red color. In contrast, blue veins are typically veins that carry oxygen-depleted blood back to the heart, which appears darker and can look blue through the skin due to the way light penetrates and reflects off the skin. However, the blood itself is never truly blue; the blue appearance is an optical illusion.
red blood cells are smaller.
None - red blood cells are also called red blood corpuscles.
White blood cells have a nucleus and red blood cells don't.

Red blood cells contain hemoglobin, but white blood cells do not
Vein color is usually dark red- not blue as commonly believed- this is a result of low oxygen content in this blood. The vein appears blue because the subcutaneous fat absorbs low-frequency light, lettling only blue wavelengths penetrate through the dark vein and reflect off. The real only difference between dark blood and brighter red blood is the oxygen content in the blood.
