You're nearly right about colour there Rhu. When I worked in the patio furniture business, I was surprised to find out that there were textile organizations that met on a yearly basis to, among other things, discuss the colours and patterns that would be popular in the upcoming years.
It is no great surprise that fashion houses often wind up having similar textiles in their lines when you know this. You'll notice this all the time...all of a sudden, every store has clothing in neon colours, or khaki, or pied-de-poule.
This colour-scheming extends to many products used everyday. The cosmetics organizations follow the colour trends closely. That is why pastel eye shadows never come out while bright neon colours are the trend and earthtoned make-up comes out when earthtoned, natural fibre clothing does.
Cars manufacturers follow the same patterns.
