Sorry for your blindness but green to red are very standard range colors for numerous things. Weather, heatmaps, elevation... What do you do for those?
I complain about them.
We are living in the year 2023.
Colorblind friendly palettes are not non existend.

Eurostat is an agency doing plots as their business. Professionals should think about coloring.
Talk about it so that people are aware of the problem and do something about it.
Thumbs up. Thanks for the reminder.
Just curious, but do the filters found in accessibility on most phones work at all to visualize this type of graphics?
Based on my experience...
No.
I dont really know why. But the thing is those filters tend to "stretch" the colorspace to make the blind colors visible.
However what would really be necessary is to create contrary contrasts.
FWIW heatmaps often use blue (cold) to red (hot).
Yes.
Or simply do black/white.
You dont need such non contrast color scales.
The max/min colors are based on their rgb:
85/15/25 %
Vs.
15/30/20 %
Does anyome really think that little shift in the red space is making a lot of contrast?
