The Colour Blue

Colours are amazing. What they are is light. Different colours are created when the different frequencies that make up white light are absorbed and reflected. Red, orange, yellow, green, blue and so on all have different frequencies.

I'm not so good at explaining the science, but here I go. The best way I know how to explain it is by using the diving example. My husband and I have our PADI scuba diving tickets. As soon as you dive down below 10m colours start to change. This is because not all the frequencies can penetrate to the depths. Red is first to go - blue is last to go - hence why the deeper you go, the bluer things are and if you have a GoPro, you need a red filter.

I'm all about colours and creation - colours are amazing. It is a gift that we are able to see colour. We have done our fair share of diving and I thought I had blue ticked off the list.

Then we visited the glacier in Argentina.

Oh my goodness! Aside from being stunningly icy, cracking, calving, monolithic and inspiring, the glacier was the bluest blue. In parts at least - the parts where the sunlight could penetrate through the drain holes, but not all the colours could. Only blue. The bluest blue you have ever seen. The only word I have to describe it is pure. Pure Blue. Amazing.

 The above is just one side of the Perito Moreno Glacier. It is a constantly moving, constantly calving (dropping ice) glacier and it is spectacular!

 The brown lines in the ice are where the glacier has picked up sediment. There is a very clear distinction between what is blue, and what is not blue!

 I really like the above shot. We trekked on the glacier for about half an hour and all I could think of what how the glacier looked like a frozen ocean. Or or frozen tidal wave.

 The bluest, purest blue you will ever see!
