You just answered it yourself. Most people you know, what about the other people? What do they use it for? Not itβs intended use, whatever it is, which is part of my point (the other part is understanding the risk of vendor lock-in).
The other people don't use it at all. They use the color selector or the default swatches.
I know no person who uses pantone seatches and does not know about spot colors. And my environment are self thought people not professional graphic designers.
