Yes, but these other ones are far more rare. Also there are shades that make it so much assessable for people. Almost every day I will ask someone what color something is because of poor selection. Chances are you have a color blind person in you office, just run visualizations by them really quick.

This is a great check, but I also recommend trying things just in greyscale as a simple test and installing something like Color Oracle [0]. Also, most of the problems can be solved by looking for an already existing solution, like swapping your heatmap colour scales for viridis [1].
The most important thing is recognising that these kinds of issues exist and pro-actively looking for good current solutions (the same applies for things like trying to ensure your site works well with screen readers).
I'd love to hear of more tools or other things that can help if people have suggestions!
