Yes. Hemoglobin is an iron-based protein within red blood cells.
When saturated with oxygen it is called oxyhemoglobin and is a bright red color. After hemoglobin releases oxygen to the body tissues, it reverses its function and picks up carbon dioxide, the principal product of tissue respiration, for transport to the lungs, where it is expired. In this form, it is known as carboxyhemoglobin and it is a purplish-red or maroon color.
Hemoglobin is red in color because it contains iron, which binds to oxygen and gives blood its red hue.
Reduced hemoglobin gives blood its red color. When oxygen binds to hemoglobin, it becomes oxyhemoglobin, which is bright red. Without oxygen, hemoglobin reverts back to reduced hemoglobin, which is darker and gives blood a deeper red hue.
Bright red
The red color of red blood cells comes from hemoglobin, a protein that binds to oxygen and gives the cells their characteristic hue. Hemoglobin contains iron, which is responsible for the red coloration.
Red blood cells contain hemoglobin, a protein that binds to oxygen. It is the iron in hemoglobin that gives red blood cells their red color. When oxygen binds to hemoglobin, the color appears brighter red.

Hemoglobin
Hemoglobin makes the red color.
Hemoglobin makes cells red since it has iron in it.
No, white blood cells do not contain hemoglobin; red blood cells contain hemoglobin (and it is the hemoglobin that gives them their red color).
