Went down the rabbit hole on this. We eat corn in two colors. Yellow and white. There are over 50,000 varieties on the planet, and they come in every color: blue, purple, red, pink, green, black. We just stopped growing almost all of them.
The colors come from three pigment families packed into the kernel. Anthocyanins, the same stuff that makes blueberries blue, produce the purples and reds. Carotenoids, the pigments in carrots and egg yolks, handle yellows and oranges. Phlobaphenes, a pigment found mostly in grains, create the red-orange shades. One kernel can carry more than one pigment at a time, which is why some of those kernels in the photo look green or multicolored.
All of it started 9,000 years ago in southern Mexico. Farmers there found a wild grass called teosinte. Picture an ear the size of your pinky with maybe 12 hard, tiny seeds on it. Every single corn variety alive today, all 50,000+, traces back to farmers in one river valley picking the best seeds by hand, planting them, and repeating that for thousands of years. A UC Davis team published a paper in Science in 2023 showing roughly 20% of modern corn's DNA came from a second wild grass that interbred with the first around 5,000 years ago. That mixing may be what finally made corn productive enough to feed entire civilizations.
The color disappeared because of money and scale. The US has lost 91% of its field corn varieties over the last century, according to FAO data. Federal grading rules say commercial yellow corn can contain a maximum of 5% non-yellow kernels. One single variety called Reed Yellow Dent makes up 47% of the genetic foundation behind modern commercial hybrids. We already saw what happens when the genetic base gets that narrow. In 1970, a fungus called Southern Corn Leaf Blight wiped out 15% of the entire US corn crop in a single season, about $7.2 billion in today's money, because over 85% of commercial corn was built on the same internal biology for reproduction. Billions of plants sharing one weakness, hit by one disease.
The colored kernels carry something beyond looks too. Purple and blue corn contain anthocyanins that fight cell damage more effectively than vitamin E, based on research in Frontiers in Plant Science. Peru grows and exports more purple corn than any country on Earth, where it goes into traditional drinks and desserts. A small clinical study from Weill Cornell found that 300mg of purple corn extract daily lowered blood pressure in people with high blood pressure over just three weeks.
The kernels in that photo are probably Glass Gem corn. A farmer in Oklahoma named Carl Barnes spent decades crossing corn varieties from the Pawnee, Osage, and Cherokee tribes to restore colors that commercial farming had abandoned. One photo of Glass Gem went viral in 2012, crashing a seed company's website with orders. Native Seeds/SEARCH in Tucson now stores nearly 2,000 rare crop varieties, including Glass Gem. Mexican farmers still grow wild teosinte at the edges of their cornfields because they say it makes the corn stronger. UC Davis geneticists confirmed that this works: pollen from the wild grass mixes with the farmed corn, adding variation back in, making it harder for a single disease to wipe everything out.

To be a humble servant of the universe, with this possibly being my purpose, and having accomplished this even in the slightest degree, has me feeling the most fulfilled in life. & has given me sense of “I can die happy.” So thank you for saying that. I’m incredibly grateful.

@yaginosenshii it’s annoying that all the conspiracy theories make perfect sense now :,) lol

It’s not a coincidence that the astronauts who’ve traveled further than any human don’t talk like they know everything. They talk like students and explorers. Their wonder and curiosity are on full display.
That’s what science does to you.
It dissolves your ego and forces you to confront the vastness of the unknown. It makes you more careful with your words, more open to being wrong and more in awe of the questions than obsessed with the answers.
It softens you in the best way possible.
