Lots of companies were making yellow DMMs before Fluke trademarked the colour.
Let's presume you buy a new car. Only, the model you selected isn't available in dark blue, because some other car manufacturer has decided it's their trademark. And you really want a dark blue one...
What happens when you run out of colours? Or what about "Black & White" registering both black and white as TM?
I'm OK with trademarks. Name, logo, form. Not colour. For the same reason generic words aren't accepted as TM. Sanity.
Nothing to do with "protecting". Everything to do with "harassing" competition.
