There is a never-ending debate in the swimming pool industry as to which color is better in the clear vs blue solar pool covers. Both pool covers are effective, but surely you might want to remove any doubt on which cover you should buy.
Even before that, you need to note that there are a lot of pool covers on the market today, ranging from clear to black to blue, and everything you can think of. But blue and clear tend to be the two most sought-after covers.
Does the Color Really Matter?
Just like the way the pool solar cover which side up matters, the color does matter when it comes to buying a pool cover. Actually, it makes all the difference.
Blue color means that less sunlight will pass via the cover into the water. And since the light finds it hard to pass; it gets trapped into your solar blanket. So, as you might have guessed, a blue cover will absorb the most light, and a clear model will absorb the least.
But simply because the blue cover absorbs more light doesn’t mean that it is better when it comes to heating your swimming pool. It’s, in fact, the opposite and this is why.
Clear Cover Absorbs Less Sunlight
A solar pool blanket cover that absorbs less light allows it to pass via into the water under it. This means that a clear cover doesn’t heat up as much as a blue or dark cover. Instead, it is the water that receives almost all the heat – it is then trapped below the cover.
A blue cover that absorbs more light also gets hotter. This heat is easily released into the air when the sun goes down. Definitely, there is a lot of heat that gets to the water but that heat later rises up into the atmosphere.
Who Wins? Clear Covers
With a blue cover, the heat that is transferred to the water leaves a layer of water just below the cover. But a clear cover ensures that the heat is evenly distributed.
A blue cover also absorbs less heat, so it doesn’t have a lot of heat to take to the water. It allows the sun rays to pass into the water themselves, without causing heat loss through interfering.
A Good Example
A clear pool cover is similar to a greenhouse that is made of glass or plastic material on the walls and ceiling. This allows the light to pass via and heat up the greenhouse. The heat is trapped under the structure, bringing out the greenhouse effect.

You might search for days trying to clear the argument of clear vs blue solar pool covers, but you won’t get a straight answer. After all, there is no scientific formula to prove this but if you take my example, you might see which one is better.
