The norwegian army have long traditions with ski troopers. From 1747 - 1826 there was even an own ski corps, consisting of one northern and one southern battallion. They were raised in the areas along the swedish border., and were specially trained for winter warfare.
The swedish infantry were usually on foot, and back then most campains were fought in the winter, because only then was it possible to cross the myriad of lakes and rivers.
The soldier in red and blue wears the 1717 uniform. The green uniform came in 1733, and was very practical in the evergreen pine forest. The king, however, didn't like it. He wanted bright red colours and more feathers. The next uniform is modell 1774. The blue one came in 1788. In 1800 came the last ski troop uniform. It had white pants, green tunic, and a white greatcoat. This is the first proper wintercamo uniform I know. See more details in this clip: https://www.youtube.com/watch?v=RvBvgM7nLHo
In 1814, Norway entered a union with Sweden, and the ski battallion lost it's importence, and was layed to rest in 1826.

In 1902, the norwegian army started tests with uniforms in natural colours. The result was the 1903 Jaegeruniform. Both Germany and Portugal requested samples of this uniform.
There was a model 1910 uniform as well in socalled "mountaingrey" colour. In 1914 a slightly modified model was adopted, and was the most common uniform in 1940. The 1934 modell was also used during ww2, but is now quite rare.
