Looks nice, but what about people who are colorblind?

stuckkeys Oct 20, 2025 View on HN

lol. What about for those that are colorblind?

Maybe consider a different color palette. I have a red/green color blindness (like ~8% of the male population), and I can only barely differentiate the colors.

You don't want to make things indistinguishable for the color-blind.

Wouldn't this disadvantage colorblind people significantly?

This is terrible for colorblind people.

Would be nice to see the referenced picture adjusted for various levels of color blindness.

I'm not colorblind, but the colors chosen are hard to distinguish.

Finnucane Oct 31, 2022 View on HN

My colorblind eyes say no. (but to be fair, that is the case for many color schemes)

That's an aggravating chart for colorblind users.
