Norrona is a great company with some really stunning designs (they are one of the few european companies I pay attention to), but their stand at the recent Friedrichshafen reflected this current marketing drive
At ISPO (the winter sports trade show) they had been selected as one of the few Gore Active Shell partners, plus they were showing off waterproof zips in a league above the majority
Six months later it seems the only thing that they can boast about is a great colour scheme. The work that I do in other industries has a general rule: when they start to play around with the colour & it becomes the focus of their marketing drive - it is because there is nothing else interesting in the product
Colour is very subjective. Black is the big seller (especially for men). No matter how well the garment performs, if it does not have coat-hanger appeal, it will not be bought. You can have the best performing & most practical design, but if the purchaser thinks that it will make them look like a geek - it will not get bought. Black is a safe option that the people who bring the ranges into the shop default to (unfortunately)
As to the accusation that the British brands are afraid of colour - I would refute that. At the Outdoor trade show in Germany I was able to catch the fashion show. There were 9 brands on show, 7 of which were clothing. 4 of those were British (Dare2Be/ Regatta, Gelert, Berghaus & Trespass). There ranges on show were (IMHO) brilliant for the european enlightened colour palate. Haglofs were another brand in the parade & the British offerings were at least as colourful
