I am curious about which stage of the design process to land on the color range to use? I can see it being helpful to commit early but there are often occasions when it can be difficult to know what you are working with until it has been completed.
If such certain rules can be set around color, why don't universal data visualization tools (like excel) have a more approachable/attractive visualization output?
Given the cone/rod performance in our eyes, should each visualization start out in black and white and then add color for emphasis from there?
