In a red country, everything is red and people are happy.

In blue countries, everything is blue and people are very depressed.

In a yellow country, everything is yellow, people are neither happy nor depressed, and their faces have no expression.

Marvin asked the mayor of the melancholy blue country: "Excuse me, why is the rainbow here not colorful but blue?"

"Rainbow? Are you talking about the one that appeared in the sky yesterday? No, no, that is not called a rainbow, that is called a blue rainbow. Of course, that thing is called a red rainbow in the Big Red Country and a yellow rainbow in the Big Yellow Country. Rainbows are only red and yellow.

, how can the three colors blue be colorful? Wuwuwu——"

Marvin said: "People in the Big Blue Country like the color blue, like to raise blue plants, like to live in blue houses, and like to wear blue clothes. These are all normal. But the rainbow in the sky is also divided into red rainbows.

A yellow rainbow or a blue rainbow is not normal."

"Why? Wuwuwu——" the mayor asked, wiping his tears.

Marvin was really not used to why these people from the Big Blue Country could be so sad all the time.

"Rainbows are colorful because of the refraction of light." Marvin answered.

"What is the refraction of light? Wuwuwu——" the mayor asked again.

"This..." Marven couldn't answer this question.

If there was a scientific picture book on hand now, Marvin might be able to explain it while flipping through the book, but it would not be easy for him to explain what refraction is out of thin air now.

Seeing Marvin tilting his head and thinking about the answer, the mayor said to him, "Didn't your parents tell you? The color of the rainbow in the sky was painted by the ancients with paint."

"Ah?" "Ah?" Marvin and Mia were surprised in unison.

The mayor looked at the expressions of Marvin and Mia and said, "You really don't know? Then I'll tell you. Wuwuwu——"

Marvin's question led to a story that happened tens of thousands of years ago.

At that time, the Triangle Star was still a unified country, and everyone was friendly and united together.

Life on the three-pointed star is exactly the same as on the earth, with one difference - the three-pointed star has no color, only black and white.

The grass is white and the trees are black.

The house is white and the land is black.

The person is white and the clothes are black.

The sun is white and the moon is black.

Of course, the black moon is invisible at night. Only during the day can people see a black disk or a black hook in the sky.

There are three moons in total. There is a moon hanging above each corner of the three-pointed star.

In addition to the black moon, there is also a black rainbow in the sky.

The rainbow at that time was black.

One day, a bird flew from nowhere.

This bird is very beautiful, its feathers are blue, its beak and talons are red, and its belly is yellow.

At this time, people on the Triangular Star realized that in addition to black and white, there are also red, blue, and yellow in this world.

The bird holds a red seed in its beak, a blue seed and a yellow seed in its two talons.

After these seeds are planted in the soil, they grow into plants that can be made into paint.

People thought that the black rainbow hanging in the sky was too ugly, so they decided to paint it with color.

Those who like red want to paint the rainbow red. People who like blue or yellow want to paint the rainbow blue or yellow.

Just when everyone was making a fuss, a dark cloud flew from nowhere and enveloped the three-pointed star.
