在大多数终端上,可以使用\033
ANSI转义序列对输出进行着色。
我正在寻找所有受支持的颜色和选项(如明亮和闪烁)的列表。
由于支持它们的终端之间可能存在差异,因此我主要对xterm兼容终端支持的序列感兴趣。
您要查找的ANSI转义序列是“选择图形渲染”子集。所有这些都具有以下形式
\033[XXXm
其中XXX
是一系列用分号分隔的参数。
可以在C语言中用红色,粗体和带下划线的文字(下面将讨论许多其他选项)来写:
printf("\033[31;1;4mHello\033[0m");
在C ++中,您将使用
std::cout<<"\033[31;1;4mHello\033[0m";
在Python3中,您将使用
print("\033[31;1;4mHello\033[0m")
在Bash中,您将使用
echo -e "\033[31;1;4mHello\033[0m"
其中第一部分使文本为红色(31
),粗体(1
),带下划线的(4
),最后一部分清除所有这些内容(0
)。
如下表所述,您可以设置许多文本属性,例如粗体,字体,下划线和&c。(StackOverflow不允许您在答案中放置适当的表格是不是很愚蠢?)

你已经有了这个!
实现端子颜色的标准从有限的(4位)选项开始。下表列出了各种终端仿真器用于这些背景和前景颜色的RGB值:
使用上述方法,您可以使用以下方法在绿色背景上制作红色文本(但是为什么呢?):
\033[31;42m
In their book "Basic Color Terms: Their Universality and Evolution", Brent Berlin and Paul Kay used data collected from twenty different languages from a range of language families to identify eleven possible basic color categories: white, black, red, green, yellow, blue, brown, purple, pink, orange, and gray.
Berlin and Kay found that, in languages with fewer than the maximum eleven color categories, the colors followed a specific evolutionary pattern. This pattern is as follows:
This may be why story Beowulf only contains the colours black, white, and red. It may also be why the Bible does not contain the colour blue. Homer's Odyssey contains black almost 200 times and white about 100 times. Red appears 15 times, while yellow and green appear only 10 times. (More information here)
Differences between languages are also interesting: note the profusion of distinct colour words used by English vs. Chinese. However, digging deeper into these languages shows that each uses colour in distinct ways. (More information)
Generally speaking, the naming, use, and grouping of colours in human languages is fascinating. Now, back to the show.
Technology advanced, and tables of 256 pre-selected colours became available, as shown below.
Using these above, you can make pink text like so:
\033[38;5;206m #That is, \033[38;5;<FG COLOR>m
And make an early-morning blue background using
\033[48;5;57m #That is, \033[48;5;<BG COLOR>m
And, of course, you can combine these:
\033[38;5;206;48;5;57m
The 8-bit colours are arranged like so:
0x00-0x07: standard colors (same as the 4-bit colours)
0x08-0x0F: high intensity colors
0x10-0xE7: 6 × 6 × 6 cube (216 colors): 16 + 36 × r + 6 × g + b (0 ≤ r, g, b ≤ 5)
0xE8-0xFF: grayscale from black to white in 24 steps
#ALL THE COLOURS
Now we are living in the future, and the full RGB spectrum is available using:
\033[38;2;<r>;<g>;<b>m #Select RGB foreground color
\033[48;2;<r>;<g>;<b>m #Select RGB background color
So you can put pinkish text on a brownish background using
\033[38;2;255;82;197;48;2;155;106;0mHello
以上大部分内容来自Wikipedia页面“ ANSI转义代码”。
由于我经常想记住什么颜色是什么,所以我有一个方便的脚本,叫做~/bin/ansi_colours
:
#!/usr/bin/python
print "\\033[XXm"
for i in range(30,37+1):
print "\033[%dm%d\t\t\033[%dm%d" % (i,i,i+60,i+60);
print "\033[39m\\033[39m - Reset colour"
print "\\033[2K - Clear Line"
print "\\033[<L>;<C>H OR \\033[<L>;<C>f puts the cursor at line L and column C."
print "\\033[<N>A Move the cursor up N lines"
print "\\033[<N>B Move the cursor down N lines"
print "\\033[<N>C Move the cursor forward N columns"
print "\\033[<N>D Move the cursor backward N columns"
print "\\033[2J Clear the screen, move to (0,0)"
print "\\033[K Erase to end of line"
print "\\033[s Save cursor position"
print "\\033[u Restore cursor position"
print " "
print "\\033[4m Underline on"
print "\\033[24m Underline off"
print "\\033[1m Bold on"
print "\\033[21m Bold off"
