Why San Francisco felt like the set of a sci-fi flick
But most city dwellers weren't seeing the science — they were seeing something out of Blade Runner.
On Sept. 9, many West Coast residents looked out their windows and witnessed a post-apocalyptic landscape: silhouetted cars, buildings and people bathed in an overpowering orange light that looked like a jacked-up sunset.
The scientific explanation for what people were seeing was pretty straightforward. On a clear day, the sky owes its blue color to smaller atmospheric particles scattering the relatively short wavelengths of blue light waves from the sun. An atmosphere filled with larger particles, like woodsmoke, scatters even more of the color spectrum, but not as uniformly, leaving orangish-red colors for the eye to see.
The uncanny images evoked sci-fi movies for a reason. Over the past decade, filmmakers have increasingly adopting a palette rich with hues of two colors, orange and teal, which complement one another in ways that can have a powerful effect on viewers.
Writing color into the script
When we dissect movies in my design classes, I remind my students that everything on the screen is there for a reason. Sound, light, wardrobe, people – and, yes, the colors.
Actor, writer and director Jon Fusco has suggested "writing color as an entire character in your script," since colors can subtly change the way a scene can "resonate emotionally."
Set and costume designers can influence color palettes by sticking to certain palettes. But art directors can also imbue scenes with certain hues via "color grading," in which they use software to shift colors around in the frame.
In her short film "Color Psychology," video editor Lilly Mtz-Seara assembles a montage from more than 50 films to show the emotional impact intentional color grading can lend to movies. She explains how different palettes are used to emphasize different sentiments, whether it's pale pink to reflect innocence, red to capture passion or a sickly yellow to denote madness.
The most powerful complement of them all
So why orange and teal?
In the 17th century, Isaac Newton created his "color wheel." The circle of colors represents the full visible light spectrum, and people who work in color will use it to assemble palettes, or color schemes.
A monochromatic palette involves tints from a single hue – lighter and darker shades of blue, for example. A tertiary palette divides the wheel with three evenly spaced spokes: bright reds, greens and blues.
Among the most striking combinations are two hues 180 degrees apart on the color wheel. Due to a phenomenon called "simultaneous contrast," the presence of a single color is intensified when paired with its complement. Green and purple complement one another, as do yellow and blue. But, according to German scientist, poet and philosopher Johann Wolfgang von Goethe, the strongest of the complementary pairings exist in the ranges of – you guessed it – orange and teal.
For movie makers, this color palette can be a powerful tool. Human skin matches a relatively narrow swath of the orange section of the color wheel, from very light to very dark. A filmmaker who wants to make a human within a scene "pop" can easily do so by setting the "orange-ish" human against a teal background.
Filmmakers can also switch between the two depending on the emotional needs of the scene, with the oscillation adding drama. Orange evokes heat and creates tension while teal connotes its opposite, coolness and languid moodiness. For example, the orange and pink people in many of the chase scenes in "Mad Max: Fury Road" stand out against the complementary sky-blue background.
Oranges and teals are not the sole province of sci-fi movies. David Fincher's thriller "Zodiac" is tinged with blues, while countless horror movies deploy a reddish-orange palette. There's even been some backlash to orange and teal, with one filmmaker, Todd Miro, calling their overuse "madness" and "a virus."
Nonetheless, given the frequency with which sci-fi films wish to subtly unsettle viewers, the palette continues to find frequent application in the genre.
As for West Coast residents unnerved by the murky air and bizarre landscapes, they're probably wishing their lives felt a lot less like a movie.

What is human dignity? Here's a primer, told through 200 years of great essays, lectures, and novels.
- Human dignity means that each of our lives have an unimpeachable value simply because we are human, and therefore we are deserving of a baseline level of respect.
- That baseline requires more than the absence of violence, discrimination, and authoritarianism. It means giving individuals the freedom to pursue their own happiness and purpose.
- We look at incredible writings from the last 200 years that illustrate the push for human dignity in regards to slavery, equality, communism, free speech and education.
The inherent worth of all human beings<p>Human dignity is the inherent worth of each individual human being. Recognizing human dignity means respecting human beings' special value—value that sets us apart from other animals; value that is intrinsic and cannot be lost.</p> <p>Liberalism—the broad political philosophy that organizes society around liberty, justice, and equality—is rooted in the idea of human dignity. Liberalism assumes each of our lives, plans, and preferences have some unimpeachable value, not because of any objective evaluation or contribution to a greater good, but simply because they belong to a human being. We are human, and therefore deserving of a baseline level of respect. </p> <p>Because so many of us take human dignity for granted—just a fact of our humanness—it's usually only when someone's dignity is ignored or violated that we feel compelled to talk about it. </p> <p>But human dignity means more than the absence of violence, discrimination, and authoritarianism. It means giving individuals the freedom to pursue their own happiness and purpose—a freedom that can be hampered by restrictive social institutions or the tyranny of the majority. The liberal ideal of the good society is not just peaceful but also pluralistic: It is a society in which we respect others' right to think and live differently than we do.</p>

The future of dignity<p>Around the world, people are still working toward the full and equal recognition of human dignity. Every year, new speeches and writings help us understand what dignity is—not only what it looks like when dignity is violated but also what it looks like when dignity is honored. In his posthumous essay, Congressman Lewis wrote, "When historians pick up their pens to write the story of the 21st century, let them say that it was your generation who laid down the heavy burdens of hate at last and that peace finally triumphed over violence, aggression and war."</p> <p>The more we talk about human dignity, the better we understand it. And the sooner we can make progress toward a shared vision of peace, freedom, and mutual respect for all. </p>
With just a few strategical tweaks, the Nazis could have won one of World War II's most decisive battles.
- The Battle of Britain is widely recognized as one of the most significant battles that occurred during World War II. It marked the first major victory of the Allied forces and shifted the tide of the war.
- Historians, however, have long debated the deciding factor in the British victory and German defeat.
- A new mathematical model took into account numerous alternative tactics that the German's could have made and found that just two tweaks stood between them and victory over Britain.
Two strategic blunders<p>Now, historians and mathematicians from York St. John University have collaborated to produce <a href="http://www-users.york.ac.uk/~nm15/bootstrapBoB%20AAMS.docx" target="_blank">a statistical model (docx download)</a> capable of calculating what the likely outcomes of the Battle of Britain would have been had the circumstances been different. </p><p>Would the German war effort have fared better had they not bombed Britain at all? What if Hitler had begun his bombing campaign earlier, even by just a few weeks? What if they had focused their targets on RAF airfields for the entire course of the battle? Using a statistical technique called weighted bootstrapping, the researchers studied these and other alternatives.</p><p>"The weighted bootstrap technique allowed us to model alternative campaigns in which the Luftwaffe prolongs or contracts the different phases of the battle and varies its targets," said co-author Dr. Jaime Wood in a <a href="https://www.york.ac.uk/news-and-events/news/2020/research/mathematicians-battle-britain-what-if-scenarios/" target="_blank">statement</a>. Based on the different strategic decisions that the German forces could have made, the researchers' model enabled them to predict the likelihood that the events of a given day of fighting would or would not occur.</p><p>"The Luftwaffe would only have been able to make the necessary bases in France available to launch an air attack on Britain in June at the earliest, so our alternative campaign brings forward the air campaign by three weeks," continued Wood. "We tested the impact of this and the other counterfactuals by varying the probabilities with which we choose individual days."</p><p>Ultimately, two strategic tweaks shifted the odds significantly towards the Germans' favor. Had the German forces started their campaign earlier in the year and had they consistently targeted RAF airfields, an Allied victory would have been extremely unlikely.</p><p>Say the odds of a British victory in the real-world Battle of Britain stood at 50-50 (there's no real way of knowing what the actual odds are, so we'll just have to select an arbitrary figure). If this were the case, changing the start date of the campaign and focusing only on airfields would have reduced British chances at victory to just 10 percent. Even if a British victory stood at 98 percent, these changes would have cut them down to just 34 percent.</p>
A tool for understanding history<p>This technique, said co-author Niall Mackay, "demonstrates just how finely-balanced the outcomes of some of the biggest moments of history were. Even when we use the actual days' events of the battle, make a small change of timing or emphasis to the arrangement of those days and things might have turned out very differently."</p><p>The researchers also claimed that their technique could be applied to other uncertain historical events. "Weighted bootstrapping can provide a natural and intuitive tool for historians to investigate unrealized possibilities, informing historical controversies and debates," said Mackay.</p><p>Using this technique, researchers can evaluate other what-ifs and gain insight into how differently influential events could have turned out if only the slightest things had changed. For now, at least, we can all be thankful that Hitler underestimated Britain's grit.</p>
