Yellow is to Black in Chinese / Japanese...

白酒紅人面黃金黑世心 literally says: [Just as] white liquor makes people's faces turn red, [So] yellow gold makes people's hearts turn black.

This is a warning about the nature of greed. The suggestion is that one who lusts for gold and riches will eventually have a black heart (or become a heartless greedy bastard). As a wall scroll, this is a reminder and warning to keep yourself from following the greedy path.

金魚 is the title for goldfish in Chinese and Japanese.

There was a time in ancient China when only the Emperor could possess the actual yellow-gold colored fish. This is why alternate coloration such as orange, black, red, and white was bred. Many believe this is why colors other than yellow-gold are more common for “goldfish” in pet shops today.

In Chinese, 平等 is the word that describes equality among all humans.

Yes, this is equality that means equality no matter of religion, whether you are rich or poor, gay or straight, black white or yellow.

In Japanese and Korean, this can be defined as equality, impartiality, and evenness (basically the same as the Chinese meaning).
