"This thing... how do you turn it on?" Zog asked.

He stared at it for a while but couldn’t figure out how to turn the lump of a thing on. Amidst the pile of wires and parts, he couldn’t see anything that looked like a switch.

"Er..." Dr. Fabric nudged the goblin beside him with his elbow, signaling for him to turn on the Magic Vision Device.

The doctor knew how to turn it on, but he didn’t dare.

’Never touch a goblin prototype that hasn’t undergone safety testing.’ This was another rule written in the "Lab Safety Manual."

It was even underlined in red, bolded, and marked for emphasis.

Goblins never thought twice about things like sparks and flashes of electricity.

The goblin engineer walked over and turned an inscription on the rune board, and the magic circuit immediately connected.

As expected, a turbulent stream of magic elements shot out from the rune board, which the goblin engineer took to the face with a blank expression.

Even more amazingly, the screen still managed to light up successfully despite this.

It seemed like anything a goblin made had the potential to be weaponized.

Next, a Magic Crystal Stone was placed into the input slot. The content was a short film specially made by the Zog Group for video-related research and testing.

Toto’s Yo-Yo Tutorial.

Yuno had been the first to use it. He had originally planned to shoot a dedicated short film that contained both varied colors and high-speed moving objects for testing purposes.

But then he discovered that Toto’s tutorial short film happened to meet these requirements perfectly.

It featured a high-speed Yo-Yo and flashy illusions.

As Yo-Yo techniques continued to evolve, new and more elaborate illusions emerged. There was even an incident where the overly complex colors and rapid changes caused a group of children to have photosensitive epileptic seizures.

In any case, once the Magic Crystal Stone was connected to the input, a colorful image appeared on the screen.

"Hooray!" Dr. Fabric cheered, pumping his fist. As far as he was concerned, the project was already a success.

However, he soon realized the atmosphere wasn’t quite right. Zog’s expression was extremely serious.

"Is something wrong?" Dr. Fabric asked nervously.

"Are you seeing a normal picture?" Zog asked in return.

"Yes, I am," Dr. Fabric replied, though he wasn’t entirely sure.

He was used to questioning himself first whenever a problem arose. Although he was considered successful in the eyes of the world, deep down, he had remained an insecure person all these years.

He rubbed his eyes to make sure he wasn’t hallucinating from exhaustion, then thought back carefully. The student assistants in the lab had all seen it, and none of them thought anything was wrong.

"What about you? Does this picture look right?" Zog asked the goblin, who was busy studying why the stream of elements had shot out.

The goblin engineer tilted his head, his confused expression indicating he had no idea if it was right or not. He was only responsible for implementing the effects the doctor required.

Zog had no choice but to activate the Magic Crystal Stone again and ask, "Is what you saw just now the same as this?"

The goblin nodded.

"Hmm..."

Zog sighed. ’What could be wrong?’

In his eyes, all he could see was a huge smear of jumbled colors, like a knocked-over paint box, with various color blocks overlapping randomly.

’That’s right—pigments!’

The types of pigments used by different races varied greatly.

Elves, for example, would claim a hundred shades of red that all looked identical to humans were, in fact, different colors. 𝙛𝒓𝓮𝙚𝔀𝒆𝒃𝓷𝒐𝓿𝙚𝓵.𝙘𝒐𝒎

According to Furin, the world she saw in her human form was different from her dragon form. She always painted in human form so that humans could see the full picture.

The fundamental reason was the difference in their visual organs.

"This Magic Vision Device of yours—what principle does it use for color display?" Zog asked the doctor.

"It adjusts the intensity of the magic flow based on the color ratios derived from parsing the color information contained within the Magic Crystal Stone, which is then used to excite the tri-color fluorescent coating on the inside of the screen, causing pixels of varying brightness to mix and form..."

There it was—the incomprehensibly long and convoluted sentence characteristic of someone from a research institute.

But Zog successfully caught the key information: primary colors. He had used the three primary colors.

Then he knew where the problem lay.

The three primary colors were primary not because there was anything special about red, green, and blue light itself, but because human vision is most sensitive to those three wavelengths.

However, Feilin wasn’t only inhabited by humans.

"You have new research to do," Zog said. "A lot of research."

If the Zog Group had any distinguishing feature compared to other organizations—besides Zog himself, the ultimate cheat code—it would be one thing.

Its racial diversity.

You couldn’t find a second organization on the entire continent that was this "correct."

Soon, a team of test volunteers representing a full suite of races was assembled, and the first-ever study into the differences in color perception among various races began.

The work progressed quickly, and the final results were simpler than expected.

Humans, Dwarves, and Halflings, being the main consumer groups, all had the same color vision.

Goblins, Beastmen, and Half-Beastmen were only sensitive to blue and green, missing one of the three primary colors. However, they could watch the Magic Vision Device just fine, because they perceived reality with a missing red hue anyway.

Therefore, the existing Magic Vision Device design could be mass-produced.

The remaining, less numerous races each had their own unique traits.

Tieflings, with their devilish bloodline, were exceptionally sensitive to red and orange. This meant that Hell, which to others was just red upon red, might appear multicolored to a Devil.

Elves, Zor, and Half-Elves, on the other hand, had tetrachromatic vision. In addition to red, green, and blue, they could also see yellow. The Elven language had several times more nouns for colors than the common tongue; what humans saw as black might truly be a riot of color to an Elf’s eyes.

Dragons were even stranger. Dragons and Dragon Descendants could see infrared and ultraviolet light, which is invisible to humanoid creatures.
