Using grey as the mid colour for this seems strange. It looks like missing data.

[–] [email protected] 9 points 11 months ago (1 children)

Would be better with a single color varying by intensity. Or at least diverging from Green, Yellow and Red

[–] [email protected] 10 points 11 months ago (2 children)

As someone who is colour blind, I hate your suggestion and love having the grey in the middle.

[–] [email protected] 4 points 11 months ago

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.

[–] [email protected] 1 points 11 months ago (2 children)

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?

[–] [email protected] 1 points 11 months ago

White would also worj

[–] [email protected] 1 points 11 months ago

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.

You could overlay this map onto the enthusiasm for permanent DST and see a pretty good pattern. Those of us on the western edge of a time zone have a lot to lose in that scenario(9AM sunrises) where folks on the eastern edges would be worse off in a permanent ST plan (3pm sunsets).

Pretty much the real reason for the time change imo. If you pick a permanent time, there are winners and losers. So… we keep doing this dumb shit.

[–] [email protected] 12 points 11 months ago (2 children)

Everyone should just switch to zulu time, and each area can set their normal operation hours. Companies don't really follow 8-5 strictly anyway.

[–] ChlorineAddict 8 points 11 months ago (1 children)

When did 9-5 become 8-5? I’ve seen it written multiple times recently.

[–] [email protected] 5 points 11 months ago (1 children)

When was it ever 9-5? My entire adult life normal working hours has always been 8-5 with a 1 hour lunch.

[–] blanketswithsmallpox 11 points 11 months ago

Permanent UTC with no timezones is where it's at.

[–] [email protected] 8 points 11 months ago (1 children)

Folks on the eastern side of the time zones wouldn’t be any more worse off with permanent ST than we already are. We already use ST in the winter when the effective daylight hours are shortest. Permanent DT would be a quality of life improvement for eastern edge of timezone folks in the winter at the expense of late sunrises for western edge of timezone people. Permanent ST I think is at least better than the switching in that it doesn’t make the short day hours any worse and gets rid of the clock change silliness.

Having the sun rise at 4 am is pretty annoying though. That's what the permanent standard time does to eastern areas.

[–] [email protected] 1 points 11 months ago (1 children)

I wake up in darkness and I get off work in darkness, and I'm in the lower 48. I hate standard time. :P

[–] Pohl 1 points 11 months ago

Time change don’t alter the angle of the earth. You don’t have enough hours of sunlight to get light at both ends of your day. It’s not standard time, it’s your latitude.

[–] [email protected] 7 points 11 months ago (3 children)

"Before 3pm" sounds horrific.

[–] [email protected] 6 points 11 months ago

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.

[–] blanketswithsmallpox 2 points 11 months ago* (last edited 11 months ago)

Seasons though.

People perpetually surprised by how far north they live will perpetually surprised me.

[–] [email protected] 0 points 11 months ago (2 children)

I imagine those regions are effectively in 24 hours of darkness at that point

[–] [email protected] 6 points 11 months ago

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.

[–] [email protected] 1 points 11 months ago

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

[–] [email protected] 7 points 11 months ago (2 children)

is there one for europe as well?

[–] [email protected] 2 points 11 months ago

The "permanent ST" lobby unfortunately had that map burned due to being pro-DST propaganda.

[–] [email protected] 6 points 11 months ago

Here in Colombia the day lengths only vary by 1/2 hour throughout the year. None of that seasonal affective disorder down here.

[–] [email protected] 3 points 11 months ago (3 children)

Are those "rays" physical or caused by timezones?

[–] [email protected] 9 points 11 months ago (1 children)

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.

[–] [email protected] 1 points 11 months ago (1 children)

Also the Mercator projection is infamously inaccurate. I'm surprised the straight lines are straight, actually.

[–] [email protected] 5 points 11 months ago* (last edited 11 months ago)

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.

[–] apex32 8 points 11 months ago (1 children)

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.

[–] [email protected] 11 points 11 months ago

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.

[–] [email protected] 3 points 11 months ago

They're caused by how the data is split on the half hour. +-1min changes color drastically.

[–] [email protected] 1 points 11 months ago

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
