My colorblind buddy said my chart's green/red legend was useless, and 3 weeks later I finally got it
I built a sales dashboard for my team and used green up arrows and red down arrows. My buddy Dev is red-green colorblind and he glanced at it and said the legend meant nothing to him. I figured he was just being picky. Then last week my manager printed the chart for a meeting and the arrows came out as two shades of gray, and nobody could read it. I swapped the arrows for up and down triangles plus a darker blue and orange, and suddenly everyone got it. I felt dumb for not listening to Dev sooner. Now I run every chart past him before I show anyone. If you have a colorblind coworker, do you actually test your designs with them, or just assume it's fine?

Ran into the same thing with our team's charts. Swapped to shapes plus a colorblind-safe palette and it fixed it for everyone, not just the colorblind folks. Never thought to run drafts past someone before though, that's a smart habit.
