Cyanosis is the appearance of a blue or purple coloration of the skin or mucous membranes due to the tissues near the skin surface being low on oxygen. Cyanosis is divided into two main types: Central (around the core, lips, and tongue) and Peripheral (only the extremities or fingers). Central cyanosis is often due to a circulatory or ventilatory problem that leads to poor blood oxygenation in the lungs. It develops when arterial saturation drops to ≤85% or ≤75% (in dark-skinned individuals). Acute cyanosis can be a result of asphyxiation or choking, and is one of the surest signs that respiration is being blocked. Peripheral cyanosis is the blue tint in fingers or extremities, due to inadequate circulation. The blood reaching the extremities is not oxygen rich and when viewed through the skin a combination of factors can lead to the appearance of a blue color. All factors contributing to central cyanosis can also cause peripheral symptoms to appear, however peripheral cyanosis can be observed without there being heart or lung failures. Small blood vessels may be restricted and can be treated by increasing the normal oxygenation level of the blood.

How low can oxygen saturation go before losing consciousness?
76 Edit to the community's answer: 76% is a lie. Mine was 76% yesterday (June 19, 2015). And I didn't fall unconscious. It is dependent upon the length of time in which you are at that saturation. If you continue to be at 76% for too long you will eventually lose consciousness. But if you are only at 76% for a minute or so you will probably be fine. Put on some oxygen and do some breathing exercises to bring your oxygen saturations up. From what I have been able to find it seems that if your oxygen saturation hits 50% you are immediately unconscious. But more likely it is dependent upon different factors and certain people might be unconscious sooner. However everyone would be unconscious at 50% If you don't have oxygen call for emergency services and do some structured breathing exercises. I have found that the best exercise to bring my oxygen saturation up quickly is to control my exhaling but to let my body inhale at the rate it wants. That is I slowly control my exhaling and but then exert no control on my inhaling. The only problem is the oxygen saturation only stays so high for a short period of time which is why you should call for emergency services if your oxygen saturation is that low. In fact anything below about 90% should probably be called in as difficulty breathing, especially if you have any symptoms of hypoxia, such as, increased rate of breathing, visual problems, trouble concentrating, fatigue, changes in mood, shortness of breath, blue lips, blue fingers tips, blue ears, et cetera.

What are quaternery colors?
Quaternary colors are formed by mixing one primary that is at 100 percent saturation with any other primary that is at either 25 percent or 75 percent saturation. There are twelve quaternary colors: cherry red, red, red-orange, orange-yellow, yellow-green, warm green, cool green, blue-green, blue, ultramarine blue, purple-mauve, and red-violet.
How do you know if you have hypoxemia?
You should use a pulse oximeter to measure oxygen saturation. Also, you can examine the finger nails or lips for peripheral cyanosis (they may appear blue) or under the tongue for central cyanosis (also blue). If you are worried that you have it, you should see a doctor or go to the emergency department of your hospital.
