Black - Blue - Clear. In that order.
But the differences between black and the other types are not very great, so many people make their choice based on other factors: - appearance (some people don't like the look of a black pool cover) - cost (some retailers charge different prices) - availability (some retailers only stock certain colors).
I would say that Blue is probably the most common.
Hope this helps ...
The greatest heat loss in any pool is from water evaporation. Any pool cover will reduce evaporation. Generally, the thicker, the better. Most high end pool covers are extruded instead of laminated. The extruded cover will last about two times longer than any laminated cover. As far as the sunlight is concerned, heat can be retained from the sun similar to the greenhouse effect. The more sunlight that passes through the cover, more heat is retained in the water. Example, if you were to paint the bottom of your pool black, more sunlight would pass through the clear cover to be absorbed into the black bottom of your pool, transfering that energy into heat. Please realize that I am getting quite technical here but I am trying to explain the physics involved. There are not very many pools with black bottoms!
Bottom line is this: The greenhouse effect to retain heat is very minimal. Therefore a clear cover may have a very small advantage...but....chloring is also broken down by sunlight. A clear cover will allow more sunlight to enter the pool, therefore shortening the cholorine life. Just my thoughts. Hope this will help. I have decided to try an extruded, clear cover this time.

A transparent cover is better for a solar heating panel as it allows more sunlight to pass through and be absorbed by the black base, maximizing heat absorption. A matte black base is preferred as it is better at absorbing and retaining heat compared to a shiny base, which may reflect some of the sunlight away.
75mm is the maximum clear cover of concrete
The boiler service and central heating system, including the radiators, are covered under the Boiler & Central Heating System Cover. The annual boiler service is also included in this. In comparison, the home cover policy has all the elements listed above but also covers problems not related to boiler heating service.
Over heating Actually - if you remove the cover from a computer - you are at risk of electric shock - NOT the computer over heating as the previous answer said !
There are a number of options when buying a central heating breakdown cover. One place to buy this is at your local heating center. There are also a number of places online where you can buy these.

The clear cover value for the RC water tank is approximately $50.
A black solar still typically works better than a clear one because black materials absorb more sunlight, leading to greater heating and evaporation within the still. This increased heat helps to speed up the distillation process and improve the overall efficiency of the solar still in producing clean water.
A Heating Breakdown Cover is used for when a heating system breaks down. One would want to be sure that this gets fixed as quickly and cheaply as possible. It would help homeowners avoid an unexpected bill.

Cloud cover does not have a temperature. It affects the rate of heating or cooling.
It is one and the same thing according to IS 456-2000
