I recently designed visuals with >5 distinct groups and was surprised that

1. Some color combinations that look very diverse for non color blind people are barely discernable for colorblind folks (like Nord Aurora)
2. There are only like 3 palettes with >5 colors out there that are widely considered colorblind safe.

Good article. Really tricky design challenge in practice, especially when other visual design axes (shape, texture) are already exhausted.

On a positive note, maybe it leads to less people flying…? Can’t have those terrible chemicals (CO2 and H2O) get into our pristine atmosphere in a huge conspiracy to heat up the planet, hardboil our eggs, and turn us all sterile.
