> if that's true then it's also shocking how little effort seems to be made to compensate for colorblindness.

Note that making something accessible to colorblindness doesn't mean you can't use color, it means you can't use color to differentiate. So a graph with a red line is fine, as long as the color isn't what tells you if the movement is positive or negative (and the graph is the magnitude, if that makes sense).

Red numbers on a excel sheet are probably fine too, as long as there is some other signifier on the cell that says "this is bad" (like parentheses or a negative sign).

Green/Yellow/Red lights on a status dashboard can violate accessibility, unless there's text or a shape that goes along with it.

Also there is varying degrees of colour blindness. I have mild case. Where I have hard time to differentiate certain shades from each other, but clearly red or green is like traffic lights is still easy to distinguish.

So something like a graph might not be an issue if shades are properly selected.
