1. Blue Is a Rare Color in Nature

We can easily say that blue is among the most favorite colors on this planet, yet it does not exist as commonly as we’d like. Even though the sky and oceans are always there to let us enjoy the glory of blue color, there is not much besides these two things in nature. There are butterflies in blue, but the pigmentation of the color is so microscopic that scientists are still researching the creation of this rare color. Even blue eyes are not precisely blue, making them the rarest eye color in the world!

2. It Looks More Like Green

Many shades of blue appear to be green, which is nothing short of fascinating. Actually, the color blue has a long wavelength with a lower frequency, making it look greener. But when it has a short wavelength with a high frequency, you’ll see more violet shade. That’s the beauty of the color blue! It keeps everyone interested with different shades and tones. If you ever wish to see pure blue color, you can locate it at 470 nanometers wavelength.

4. Blue Food Is Considered to Be Poisoned

We think humans are more fascinating than the color blue! First, we associate this color with calmness and tranquility, but when we talk about blue food, it’s more or less poisonous as far as human beings are concerned.

This superstition comes from centuries-old beliefs, which many brands are trying to dispel with a lot of marketing. Maybe that’s why we are, sort of, okay with blue sweets nowadays.

5. Rayleigh Scattering Makes the Sky Blue

The sky does not appear blue during the daytime on its own. It has to thank the Rayleigh scattering effect for the beautiful color. Rayleigh scattering occurs when particles are electrically polarized, making them move at the same frequency. This effect works on sunlight when it enters Earth’s atmosphere, causing diffuse sky radiation. It results in daytime blue color. The same effect is also why we see the sky in the yellowish shade when the sun is low.

6. It Is One of the Three Primary Colors

Besides red and yellow, blue is a traditional primary color. You can make green using yellow and blue, and violet with red and blue. Blue is also a primary color for paintings and their pigments. Most artists considered this color to be precious and pure, only using it to accentuate the uniqueness of their art pieces. Even in digital media, blue is part of the primary colors that make digital colors possible. A computer can create multiple tones and shades of colors with RGB’s blue.

7. Blue Color Is a Latecomer Among Other Colors

Artists and fashion designers have been using the prominent natural colors for centuries, but blue was not their radar for a long time. It was a latecomer in art, fabric, and decorations, along with literature and language. If we look at old cave paintings, we’d see more shades of brown, black, and red, but no shade of blue. Even for fabric dyes, red, pink, and purple are more common than blue. Maybe the difficulty in creating the correct pigmentation of blue is what makes it so rare in everyday use.
