Using grey as the mid colour for this seems strange. It looks like missing data.
Would be better with a single color varying by intensity. Or at least diverging from Green, Yellow and Red
As someone who is colour blind, I hate your suggestion and love having the grey in the middle.
Usually for single colors we should use blue. The green, yellow red is a standard business practice that is terrible design but now a convention.
Would you mind elaborating for someone who also does graphs a lot and tries to keep them colorblind friendly? What makes the grey easier to distinguish than (say) just white?
Here is a good resource I have used in the past for visualizations that I tried to make color blind accessible. (I have tritanomaly and I have worked with and designed some visualizations for folks that are red-green color blind.) https://colorbrewer2.org/#type=diverging&scheme=BrBG&n=3
I feel like this particular map would work better for a sequential color scheme than a diverging one. But either way there are several suggestions that will work. For a diverging color scheme, you just really want the middle color to be more neutral. Gray, beige, and white all work.
White would also worj
“Before 3pm” sounds horrific.
I live in the Arctic and polar night is the most beautiful time of year. The sun almost comes up and paints the clouds red, while the sky to the north is stained purple. Then at night you frequently get the aurora and even if you don’t you get a beautiful crisp starry night surrounded by snowy mountains.
Seasons though.
People perpetually surprised by how far north they live will perpetually surprised me.
I imagine those regions are effectively in 24 hours of darkness at that point
You’d be surprised what some sunlight will do vs none at all. But the light that does come is very low on the horizon making it feel like sunrise/sunset and then it’s gone again.
I can’t tell you about 24h of darkness, but I would love to experience a few weeks of 24h daylight! But only as a tourist. LOL
is there one for europe as well?
The “permanent ST” lobby unfortunately had that map burned due to being pro-DST propaganda.

Here in Colombia the day lengths only vary by 1/2 hour throughout the year. None of that seasonal affective disorder down here.
Are those “rays” physical or caused by timezones?
Remember that the world is tilted as it rotates. The “rays” are from the earth’s rotation at an angle changing the sundown time on an axis.
Also the Mercator projection is infamously inaccurate. I’m surprised the straight lines are straight, actually.
This is absolutely not Mercator (otherwise, meridians would be all vertical and the Polar Circle a straight horizontal boundary), and the diagonal lines do not quite appear straight.
The timezones are the thick grey lines on the map, and you can see they are causing breaks in the “rays”.
I’m not sure what’s causing the rays.
Going south makes the earliest sunset happen later (because every sunset happens at the same time at the equator) and going west within a timezone makes it happen later too (since the sunset moves from east to west). Put those together and you get the diagonals.
They’re caused by how the data is split on the half hour. ±1min changes color drastically.
I think we’ll be close to 16:00 here by the time we hit the shortest days of the year. Sunset is 16:29 tonight.
In the summer, the sky is getting light at 4-4:30
