Speaking of imperial purple, today I say a color that does not have a strong sense of existence - gray gray/grey.
Gray, we really rarely use it, and we also hate gray, hate the gray sky, hate the accumulation of ash, in short, hate everything about gray. So, we really don't like gray!
However, the "Fifty Shades of Grey" movie that caught fire some time ago made everyone re-recognize the word grey. In fact, the English of the film is Fifty Shades Of Grey, and Grey "Grey" refers to the surname of the male protagonist Gray, and also refers specifically to the shadow left by the childhood experience of the male pig's foot. On the palette, 50% black and 50% white are exactly gray, which also implies that human nature is not black or white, so it is also appropriate to translate it as "fifty shades of gray".
And in PS, when the saturation of gray is adjusted to 50 degrees (50%), the photo that comes out is the closest to the real color. Metaphor SM is a real phenomenon in reality.

Here's a passage from the Xinhua report:
We also vowed to crack down on and ban illegal income, regulate off-the-books income, gradually form a transparent, fair and rational pattern of income distribution, and resolutely reverse the widening income gap。
We are committed to strictly prohibiting and cracking down on illegal income, regulating gray income, gradually establishing a transparent, fair and reasonable income distribution model, and resolutely reversing the trend of widening income disparities.
off-the-books income is income that is not recorded outside of the normal administration of tax evasion. Books here means "book of accounts", and off-the-books means "unrecorded". "Black income" is illegal income; "white income" is elite income; gray indicates that it is between black and white, that is, between legal and illegal.
