REPUBLIKA.CO.ID, JAKARTA—Humans can enjoy the beauty of various variations color interesting thing on earth. Would the same colors look similar on another planet?
The human brain basically has an extraordinary ability to adjust vision in various lighting conditions. For example, when wearing sunglasses, people may initially see everything a little darker. But gradually, these colors will look “normal” again.
Similar adjustments also occur when humans enter old age. As is known, as you get older, the lenses of your eyes become more yellow. Even so, elderly people tend not to notice any changes in the colors they see because their brains have already made adjustments.
The brain’s ability to adjust and interpret colors when on another planet is not much different from when on earth. The brain will make the colors on a planet look more natural.
On Mars, for example, the dominant color nuance on the planet is red. When astronauts set foot on Mars, a red glow may be visible around them. However, as time goes by, the terrain on Mars will appear to change from red to brownish or grayish.
“And the ocher (dark yellow or orange) Martian sky will start to look bluer, not the same as the blue on Earth (sky), but the orange color will be much less orange than what we see now,” said a cognitive vision scientist from the University of Nevada, Michael Webster, as reported LiveScienceon Monday (25/9/23).
Of course, not all skies on various planets will turn blue to human eyes. The color changes or adjustments that occur will depend greatly on the dominant color of a planet. The sky on Mars will appear to turn bluer because the opposite of orange on the color wheel is blue.
“If you could travel to an exoplanet with purple plants and gold skies, for example, your brain might make different adjustments,” continued Webster.
Color adjustments by the human brain are not only limited to hue or color hue, but also intensity. On planets with a limited natural color palette, the brain will also make changes to color gradations. Colors that initially look faded on a planet will gradually appear brighter.
“(On the other hand) if you live in a very colorful environment, you will reduce (the intensity),” said Webster.
Hypothetically, humans could predict how light would interact with color in a planet’s environment. This prediction can be made as long as humans can know the composition of the atmosphere or ocean on a planet.
By utilizing computer algorithms, scientists can adjust the color and attach it to the part visor in astronaut suits. That way, astronauts can see the various colors on the foreign planet they visit more naturally.
However, all of this is of course still a theory. As long as humans have not set foot on another planet, it is difficult to truly ascertain the color adjustment process that might occur when humans are on another planet.
Not only on other planets, various colors can look very different when humans dive into the ocean. Oceanographer and engineerDerya Akkaynak, experienced this firsthand when diving to a depth of more than 30 meters.
Akkaynak revealed that red light could not reach the depths of the water. Therefore, everything he saw when diving at a depth of 30 meters was yellow, not blue. “Maybe because my (brain) is trying to compensate for the lack of red. But in general, everything looks crazy,” said Akkaynak.
