Why is the world losing color?

I live in South Africa, and when I traveled to the Netherlands on holiday last year, I was quite taken aback at how muted everyone's clothing was.

It is definitely not like that here - everything from our flag down is full of color.

Sample size of two, but when I went to Costa Rica and then China, I did not get the sense that color was going out of fashion in either place. Indeed it seemed jarring how cOLorFuL everything was. But after a week I got used to it.
