Why does the blue shower curtains look so good?

It was one of those moments when you realise just how easy it is to put on a new pair of shower curtains for the first time.

The blue hue gives them a warm, natural look, even though they are not really made for showers.

But there is another, hidden side to these curtains, too.

They also give a different colour to the water when it hits them.

The result is the same colour as the curtains themselves.

A new pair will cost about $150, depending on how well they look.

It will be an investment that will last a lifetime.

Here are some tips for buying a new set.
