I look at marketing material prepared with stock images and fashion catalogues. What do I see? Lots of white faces. Maybe there is a picture in there somewhere of some black girl playing with young Tarquin (who is obviously white). The word 'tokenism' springs to mind.
I don't believe most people care less about what colour people are, however, if you use a lot of stock photography, step back, look at the body of your work and wonder why all the faces are white. It happens. Sometimes all the images that are supplied are of white people, yet you may not notice this until, for some random reason, you get a person of colour showing up. Then the '98% white' trend is revealed.
The thing is that not everyone wants to be white. People might want to be young, thin, beautiful, with a full head of well groomed hair - that is aspirational. So you can keep the old, fat and ugly people out of the marketing material - that is fine. But to consciously or otherwise end up with only white faces is where TV was more than a generation ago. We should have moved on, perhaps even more so than TV as the internets is global rather than parochial.
