最近搞命令行配色被灰色迷倒，捋清楚了之后写了个 wiki： https://github.com/g6ai/dotfiles/wiki/Colour#grey

这里搬运 wiki 内容，链接里排版更舒服一些，如果有更多分享的内容也会更新。

Grey

True colour Grey

There are two Grey colours:

• #bebebe in X11, 75% brightness
• #808080 in HTML, 50% brightness

And the other three variations of Grey is derived from the one in X11, so together they make a range of Grey colours:

• #d3d3d3, LightGrey, 83% brightness
• #bebebe, Grey, 75% brightness
• #a9a9a9, DarkGrey, 66% brightness
• #696969, DimGrey, 41% brightness

In (at least) Vim colour schemes, the Grey in HTML is actually used. So the Grey range actually applied is:

• #d3d3d3, LightGrey, 83% brightness
• #a9a9a9, DarkGrey, 66% brightness
• #808080, Grey, 50% brightness
• #696969, DimGrey, 41% brightness

So the Grey is darker than DarkGrey!

256 colour Grey

For terminal emulator that do not support true colour (better not use such terminals, but there are always those scenarios where you have to deal with those), the best replacement for the Grey range is listed here:

True colour	256 colour
LightGrey, 83% brightness, #d3d3d3,	#d0d0d0, 252, 81% brightness
DarkGrey, 66% brightness, #a9a9a9,	#a8a8a8, 248, 65% brightness
Grey, 50% brightness, #808080,	#808080, 008, 50% brightness
DimGrey, 41% brightness, #696969,	#6c6c6c, 242, 40% brightness
