As concerns grow over disruptions in global supply chains and petrochemical products, it is worth asking how much of the color around us is truly necessary. A simple morning of sorting plastic waste led me to reflect on the difference between artificial colors and the colors that nature provides.
Today was plastic recycling day.
Collecting trash from around the house and taking it out is one of the small household chores I help with.
I have become reasonably good at sorting bottles, cans, paper, and other recyclable materials. However, I still do not fully understand how to dispose of hazardous waste or certain plastic products.
As I looked at the plastic bag holding the collected waste, I found myself wondering how long such bags would continue to be readily available.
While stuffing plastic packaging into it, I was struck by how colorful those packages were.
Do we really need all this?
Of course, there is no doubt that color has enriched human life throughout history.
Looking at the cave paintings of Lascaux or the murals of the Takamatsuzuka Tomb, one can see that people have sought color since ancient times.
Human life must always have been filled with color, and people must have worked hard to obtain beautiful pigments and dyes.
Today, we can create almost limitless shades and tones, and products are designed with an endless variety of colors and patterns.
Not only plastic packaging, but entire cities are overflowing with color.
Yet the materials that support many of these artificial colors may become harder to obtain. If tensions involving the United States, Israel, and Iran were to disrupt shipping through the Strait of Hormuz, supplies of naphtha and related petrochemical products could be affected.
But how much of this is truly necessary?
When the sun rises, the world is filled with color. When it sets, another day comes to a beautiful close.
Each season brings its own colors as well, surrounding us throughout the year.
Of course, some color is essential to daily life.
Yet it sometimes feels as though modern society has become overwhelmed by color.
Even if artificial colors became more difficult to obtain, perhaps we could continue our lives by appreciating the natural colors already surrounding us.
Then again, even those “natural colors” are increasingly shaped and enhanced by human hands. In a world where nature itself is often managed, designed, or recreated, the boundary between natural colors and artificial ones seems to be growing ever more uncertain.
Perhaps the question is no longer whether a color is natural or artificial, but whether we still notice the colors that matter.
