The red blood cells don't loose hemoglobin. Hemoglobin is the protein the oxygen binds to. So I think a better question is " What is the colour of RBC's without oxygen?" And the answer in a dark red.
Red blood cells (RBCs) contain a protein called hemoglobin, which binds to oxygen and gives them their red color. When RBCs are oxygenated, they appear brighter red, and when deoxygenated, they appear darker red. This is why blood in arteries, where oxygen is bound to hemoglobin, appears brighter red compared to blood in veins.

The hero here is hemoglobin! Hemoglobin is on Red Blood Cells (RBCs). RBCs are one component of blood. Everytime your heart beats, it pushes oxygenated blood to all parts of your body.
Normochromasia on a stained blood film indicates that red blood cells (RBCs) have a normal concentration of hemoglobin, resulting in a typical color and appearance. This finding suggests that the RBCs are adequately oxygenated and functioning properly. It contrasts with conditions like hypochromia, where the RBCs appear paler due to lower hemoglobin content. Normochromasia is often associated with healthy red blood cell production and overall good iron status.
Only Red Blood Cells (RBCs) contain hemoglobin. The white cells do not and the platelets (fragments of cells) do not.

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.
Hemoglobin is a molecule in our red blood cells of the body (RBCs) used to transport oxygen (O2) through the blood. When the body needs more O2 supply to its tissues, such as when there is too much carbon dioxide (CO2), our bodies produce more RBCs and thus more hemoglobid for that extra O2 needed. In cases of carbon monoxide (CO) exposure which is toxic to humans, the same type of thing happens. You can notice exposure to CO by looking at the skin color on a person. Because hemoglobin gives RBCs their color, a person who has been exposed to CO for a period of time will look red in certain areas on their skin due to the increase in RBC/hemoglobin in the blood.
Red Blood Cells (RBCs) have hemoglobin. Hemoglobin picks up oxygen, like giving a piggy-back ride. The RBCs in the blood circulate throughout the body.
They haemoglobin pigment present in the blood gives it the red colour.this pigment is found in the RBCs hence making them red in colour.
The red color of hemoglobin molecules is a physical property. It arises from the way hemoglobin interacts with light due to its molecular structure and the presence of iron ions, which absorb certain wavelengths of light and reflect others. This color can be observed without altering the chemical composition of hemoglobin.
