If such a thing is allowed, it will be a big profit. In fact, the specifications of personal computers with a market price of about 60,000 yen are disguised as specifications equivalent to 300,000 yen and sold at a price of 150,000 yen.

For example, the human eye is most sensitive to green light with a wavelength between 520 and 570 nm in the visible spectrum, which makes red or blue less sensitive, while green light of the same wattage is brighter than other colors.
