"What's going on?" Tang Chu asked.

"Miss, you're here, little one has good news for you." Song Yu's face was full of colorful paint, and only a mouthful of big white teeth and shiny eyes showed a smile.

Tang Chu was immediately overjoyed when he heard this, this is the development of cyan rouge!

Yes, cyan rouge, it is said that blue is better than blue, cyan rouge is extremely difficult to make, once you make a mistake, it is either dull or too dark, and it is extremely ugly to apply on the skin.

Song Yu and the five sons behind him looked at Tang Chu with a smile, Song Yu couldn't hold back the excitement in his heart, he turned around and picked up a plate of freshly made rouge on the desk.

The rouge had not yet been dehydrated and was currently in the form of a cream, but it had taken everyone's eyes away from it.

"This is ......" Before he finished speaking, Tang Chu covered his mouth, and then exclaimed.

"Oh my God!" Tang Chu looked at the rouge in Song Yu's hand in disbelief.

"It's actually a blue color," Tang Chu muttered.

She carefully took the rouge handed over by Song Yu, her eyes condensed on it, and there was a shocked look on her face.

The women of the Heavenly and Kingdom all know that this rouge is divided into face fat and mouth fat.

Most of the lip fat is red on the lips, and the face fat is mostly red, and it is applied to the cheeks to show a rosy complexion.

Over the years, the ladies in the palace have taken the lead in using cyan, blue, and inky rouge to apply to the eyebrows and eyes in order to fix their pets, making the makeup more charming and changeable.

The people rushed to follow suit, but due to the limited skills, the rouge produced was always unsatisfactory.

This blue rouge is even more rare, because this is a rare color in the heavens and the country, not to mention the people, even the number in the palace is extremely rare, and the only few boxes are still paid by the Persian country every year.

Tang Chu lightly smeared a little rouge on his eyebrows, and the fat powder was delicate and quickly blended.

Tang Chu's eyebrows are very good, and after applying this blue rouge, his skin is even fairer, and his eyebrows and eyes are moving.

"Miss, I've never seen rouge double happiness of this color, but it really looks good." Shuangxi couldn't help but sigh when she looked at her young lady after applying makeup.

"This is teal, extremely rare, I didn't expect it to be made in my Tang family!"

Tang Chu was still a little excited, she couldn't stop stroking the rouge, and she couldn't wait to increase production immediately.

After a while, Tang Chu calmed down, and she asked with a smile, "Song Yu, can you tell me in detail how this color is made?" ”

Song Yu waited for Tang Chu to ask him, only to see him salute and say, "Miss, the preparation of this color is really lucky, let's start from the beginning." ”

Tang Chu nodded and motioned for him to continue.

Shuangxi brought a chair from nearby, and Tang Chu sat on it and listened.

"Miss, here's the thing." Song Yu began to tell the story.

"Originally, the plan for the past two days was to make cyan rouge, but I tried it with the Tang family several times and failed, and I couldn't get the right color after thinking and meditating, and every time it was a little bit worse."

As he spoke, Song Yu picked up the rouge that had failed before and showed it to Tang Chu, "Miss, please see, this is the color that was concocted before." ”

Shuangxi also poked her head to watch, but she was confused when she saw it, "Song Yu, aren't these colors the same, they are all cyan!" ”

Shuangxi really can't figure out what the difference is with these boxes of failed rouge, obviously they are all cyan in her opinion.

Tang Chu was instantly amused when she saw Shuangxi's puzzled appearance, and she didn't hurry to ask Song Yu to take the painting paint for comparison.

A small box of pigment was opened and placed next to Song Yu's failed rouge, and even Double Happiness was clearly visible.

She leaned closer and carefully compared the colors, and it was really different.

"There are really subtle differences, and Song Yu is either a little deeper or a little shallower." Double Happiness said.

"Yes, although it can be confused with the real, the subtle differences can be distinguished at a glance in front of the connoisseur." Tang Chu said.

"Miss, in this way, the cyan rouge I bought before was fake, I feel that the box of cyan rouge I bought at the rouge shop before and Song Yu failed to concoct the same color" Shuangxi couldn't help but feel a little regretful.

"It is indeed possible that it is a fake, if there is no comparison, normal people can easily recognize these colors as cyan, and the rouge shop will also sell it with fake or fake for profit." Tang Chu explained.

"Oh, it's so disturbing, the slave spent so much money to buy a fake." Double Happiness is extremely regretful, there is nothing more disturbing for a woman than buying a fake.

Seeing this, Tang Chu comforted, "Silly girl, what are you still feeling sorry for, our Tang's Rouge Shop is about to open, and the rouge will be produced and sold by itself in the future, are you still afraid that you will use fakes?" ”

Hearing this, Shuangxi's mood suddenly turned cloudy and sunny, and his eyebrows were full of smiles, "I knew that Miss treated me well,!" Don't worry about rouge in the future! ”

Tang Chu affectionately knocked Shuangxi's forehead, causing the other party to laugh uncontrollably.

The master and servant didn't joke for too long, and Tang Chu still remembered that Song Yu hadn't finished talking about the topic just now.

"Song Yu, you go on, how is this blue color made?" Tang Chu was very interested in this, and she knew very well how much opportunity it would bring to the Tang Clan if such colors only appeared here.

Song Yu continued to begin his narration, "The little one was already a little frustrated after many failures, so he left the workshop and went to the front hall to let off steam, and at this moment I saw a few pots of Molan from Zhuangzi. ”

"A small whim, if it is mixed with the juice of Mo Lan, what color will it come out? The small one mashed Mo Lan and added the filtered juice to the failed cyan rouge, who knew that the first experiment made this azure. ”

Song Yu's words were mixed with joy, but anyone could hear the hardships of the modulation process, trial after experiment, modulation ratio again and again, no direction, no eyebrows, what should a person's heart be blocked?

However, the god of luck still came, Song Yu's idea was very positive, and he accidentally matched it into a more rare blue color.

Everyone present may not have imagined the huge benefits brought by this incident, but Tang Chu already had a plan in his heart.

After listening to Song Yu's story, Tang Chu asked eagerly, "Do you remember the ratio?" ”

After all, it was made by mistake, Tang Chu was still a little worried, if Song Yu didn't remember the ratio, but just concocted this small dish, then wouldn't she be happy in vain.

"Miss Hui, I will record the ratio of each concoction, although this time it is a simple attempt, but I am used to recording, and the small one still writes down the ratio this time."

Song Yu gently took out a booklet from the cabinet, which was densely packed with records of successful blending of various colors.
