As a colorblind person, fuck whoever decided on the colors for this image. I hope they meet a very angry porcupine.
I know your comment was a joke, but am I right in saying dogs see monochromatic pictures in yellow and blue as opposed to black and white?
Can you provide some detail on your comment? As a non colorblind person, I would like to understand how this image could have been modified to include our colorblind brethren.
I am red-green colorblind. So certain shades of colors like that I literally can’t see. Blue and purple are issues, and certain shades of yellow and green.
In the image above, I cannot really see a difference in the extremes of the legend. The gradient is definitely not helping. I can see the difference when put near each other. Like Mississippi and New Mexico are clearly on opposite sides, but I would not be able to tell you which direction either leaned because I can’t see what the legend is showing. Likewise most of the states mean nothing to me since they’re part of the gradient itself going towards colors I can’t distinguish a direction from. Without the numbers, this map would mean nothing to me.
Simply put, pick colors on opposite sides of the color wheel when trying to show differences like this with gradients and you’re more likely to to okay. Don’t pick colors that are next to each other. TRhis might as well have been a blue/purple gradient with an extra z-dimension for time or some crap,
It’s not gray, almost no one actually sees in greyscale, despite the jokes. It’s always just certain shades the eyes can’t distinguish differences from.
A good example for other common colors, is peanut butter looks like a shade of like greenish tan or maybe dark khaki, not brown as most people describe it to me.

Hey there, sorry to bother you even more, but I’ve got a follow up question. You said working with complementary colors (“opposite sides of the color wheel”) might work better, so in general it’s easier to distinguish for red-green colorblind people. I’ve always thought it was especially hard to distinguish red from green in those cases, but red and green are complementary colors. Where did I go wrong here? Is it something I misunderstood from your explanation or is it my understanding of red-green colorblindness that’s just wrong?
Thanks for the writeup! If I were giving a presentation explaining the Four Color Theorem, which four colors should I choose to accomodate folks with colorblindness?
It looks like going from blue (-20) to white to blue (+20). It could be modified by using a different color palette - for example blue/green, blue/red, yellow/blue. A good indicator is also if the colors are still discernable in grayscale altough this will be pretty much impossible on a divergent color scale unless you add a second identifier such as dots.

In general it is a good idea to use colour gradients that monotonically increase (or decrease) in brightness in addition to (or instead of) hue (see here for an in-depth comparison of different colour maps. It’s from a Python package, but it shows some interesting plots comparing different colour maps when it comes to brightness vs. hue). This isn’t just useful for colour blind people, but also helpful when printing in black-and-white.
If you absolutely have to use a diverging colour map, you might reach most people by using blue as a major component of one, but only one of the two branches (the map in the OP uses blue as a major component of both branches, which is why red/green colour blind people can have a problem with it). That way most colour blind people should be able to distinguish the branches, since blue colour blindness (Tritanopia/Tritanomaly) is much rarer than red (Protanopia/Protanomaly) or green (Deuteranopia/Deuteranomaly) colour blindness.
Apart from that it is also possible to mark information visually in other ways than by colour, e.g. by shapes and patterns, like dotted or dashed lines for line graphs, shaded or dotted areas for bar and area graphs, or different geometric shapes like crosses, diamonds, and circles when plotting individual data points, but that is probably more useful when different sets of data are plotted in the same graph.
Assuming you’re on a phone, do you not have a colourblind filter in your device’s accessibility settings? I introduced a colourblind mate to that a few years ago and he was blown away.
Wow the right didn’t decide barbie was woke?
No, didn’t you see the article that it leans too much on heteronormative ideology?
LOL so the right crazies hate it because it’s too woke, the left crazies hate it because it isn’t woke enough, but most people enjoy it because it slides somewhere in the middle?
The South needs to sit down with itself and discuss their issues.
They did, and decided to blame it all on those “darn liberal city slickers with their fancy book learning”.
Source: Right now they’re literally blaming books for their problems, and are banning and burning them.
Conservatives all blame someone or something else for their problems, and even dismiss them exisiting until it happens to themselves or someone close to them.
Abortions are the devils work and anyone who aborts should rot in hell and misery. Except for my little Angel that made a honest to god mistake that shouldn’t ruin the rest of her life.
While most of the states with zero are searching for both equally, I get the feeling that Wyoming is zero because no one searches for either.
Probably not surprising tht Oppenheimer is furthest ahead in New Mexico. But why is Mississippi so into Barbie?
I assume because Mississippi is so horrible they need escapism to mentally survive. It’s also possible there are more families with young children in the South.
Los Alamos is worth a visit. The lab is locked down (a road goes through it, you are not supposed to take pictures), but there are a couple really neat museums. One of the retired age volunteers at the museum asked us how deep of a discussion we wanted. He went down a deeep rabbit hole of chemistry and mechanical bomb design. It was obvious he had strong knowledge of how atom bombs worked. It was glorious. And the boys boarding school is also neat.
