Chapter 499

Su Haitang motioned her to rotate the card an angle.

"See? There's a very beautiful light at the head here. What color do you think it is?"

"Lavender?"

Xuanyuanmin squinted uncertainly.

"Let's show it to my uncle." Su Haitang smilingly talked about it.

"Can you see the flowers? I'm not color blind."

Xuanyuanmin complained a little and gave the card to her husband like a stream of good advice.

Su Junyue turned the card carelessly, and the elegant Danfeng's eyes opened wider and wider!

"What's going on? I look bright yellow!"

"Impossible!" Xuanyuan min leaned over and looked at them together!

"It's lavender, a little pink." xuanyuanmin stressed.

"Bright yellow, very obvious." Su Junyue firmly stressed.

"What's going on?"

The couple looked at each other and asked about the smiling Su Haitang.

"It's just a cover up." Su Haitang smiled.

"Talk while eating." Su Haitang took the initiative to say hello.

"To put it bluntly, it's not worth anything. Light is roughly due to the combination of seven color spectra, but it blends into transparency."

"For example, diamond cutting and making some angles can refract bright light, be captured by our retina and form a bright color feeling."

"People's retina is as different as fingerprints. Coupled with the habit of using eyes after tomorrow, there are more or less problems, such as myopia, astigmatism, the speed of optic nerve response and so on."

"Anyway, it's probably such a principle. Some special patterns will show subtle differences in the eyes of different people. I mistakenly expanded this difference infinitely."

In fact, it was her whim to do the experiment, take out a little cold spring water, add the five kinds of leaves of the five color tree, and take a little dust particles of the space stars. Then the cold and heat acted violently, and a little dust powder after the explosion was mixed into the card raw materials, which was just a magical phenomenon.

Just used by her for anti-counterfeiting.

It's just that this unexplained coincidence can only happen once. Otherwise, what should she do if she is asked to design anti-counterfeiting coins? Where did she come up with a rigorous and reasonable scientific explanation?

"Is it so magical?" xuanyuanmin happily looked back and forth at the card. It was lavender.

Su Junyue looked at Su Haitang with deep eyes and frowned slightly.

"Do you still have this card? Give me one. I'll call those old men in the Department of physical chemistry and optics to study it."

Su Haitang was not afraid of revealing his stuffing at all. He trotted out another one and offered it with both hands.

"Let me see."

Xuanyuan min came together and the couple looked for the right angle like turning a thermometer.

"Blue purple."

"Dark gold."

The couple looked at each other and looked serious.

"You may have other uses for this thing. When the VIP card is issued, it's too overqualified. Take out all of it."

"Write a detailed report on your formula and production process, and I'll hand it in. Don't worry, I won't take you for nothing."

Xuanyuanmin opened in a positive color.

Su Haitang was actually ready for this.

It's just this. It's too tricky. She didn't decide whether to report it.

It's hard to take credit for not knowing the principle and not being able to copy it successfully.

Unless she reports the secrets of space.

But in this way, she will become a national treasure level key protection object, and her freedom will be limited, just like Su Haiyan.

She doesn't want to take the risk. It's totally unnecessary.

"Do you think this is useful?"

Su Haitang smiled and explained.

"I thought I had inadvertently made a great super invention and wanted to ask for credit. Unfortunately, I wanted to break my head and remember. I tried hundreds of times, but I still didn't succeed."

"It was an accident."
