I compared a red-green palette to a blue-orange one on my last dashboard
Had to build a sales dashboard for a colorblind client in Houston. First attempt used red for losses and green for gains. Looked fine to me. Client said it was just two shades of brown. Swapped to orange for losses and blue for gains. He could read it instantly. Anyone else found a specific palette that works better?

Jump right into something nobody's thinking about - the color blindness types themselves. @king.dakota, you mentioned contrast, but here's the thing: red-green issues cover a few different flavors. Protanopes see reds as darker browns, deuteranopes see greens as lighter browns. I had a client who was a tritanope - blue-yellow colorblind. That blue and orange palette you settled on would've been just as useless to him as red-green was to your first client. He could read a purple-yellow combo though, since those stay separate for tritanopes. Best approach I've found is to ask the client what specific type they have before picking anything.

Wait, TWO SHADES OF BROWN? That's honestly wild to me. I never even thought about how that red/green thing could look so different to someone else. But yeah, blue and orange is a solid combo. It's got enough contrast that even folks with regular vision can appreciate it.

Heard a podcast once where a designer said something like 8% of men have some form of color blindness, so it's way more common than people realize. Makes me wonder how many websites and logos are just mud to a huge chunk of the population.
