"But the thing that really captures your attention," Tom says, "are the colors."

To paint the picture, I would start with the palette.

When you travel the seas of Norway, you have the North Sea, the Norwegian Sea, and at the top, the Barents Sea.

And each of these has its own color, and the colors of the water are just unbelievable.

And you could probably bring to mind the color of a Norwegian fjord, the unique blue in the summertime, perhaps, where the greenery of the mountain just jets vertically down into the blue fjord.

And the reality is that in the autumn and the winter, the snow and the rock itself induces shades of color in the water, greens and blues that you'll never see anywhere else.

There's a kind of arctic blue that I absolutely love.

And then, just in front of that river of stars, something starts to move.

Another interesting thing about the Northern Lights is that they don't always look the same.

you can see how the lights move in a variety of different ways.

So they can be very docile, they can be very placid, they can be an arc on the horizon.

I remember trying to show my mum the Northern Lights once in Iceland, and she thought it was a cloud.

And it did look like a cloud.

It looked to me like the Northern Lights, but that was only because I had the benefit of experience.

It took a while for her to identify any movement.

Wonder.
