Since I’m often in the position of trying to remember what colours are what, I have a handy script called: ~/bin/ansi_colours: #!/usr/bin/python Much of the above is drawn from the Wikipedia page “ ANSI escape code“. Support for “true color” terminals is listed here. So you can put pinkish text on a brownish background using \033[38 2 255 82 197 48 2 155 106 0mHello

Now we are living in the future, and the full RGB spectrum is available using: \033[38 2 m #Select RGB foreground color The 8-bit colours are arranged like so: 0x00-0x07: standard colors (same as the 4-bit colours)Ġx10-0圎7: 6 × 6 × 6 cube (216 colors): 16 + 36 × r + 6 × g + b (0 ≤ r, g, b ≤ 5)Ġ圎8-0xFF: grayscale from black to white in 24 steps Using these above, you can make pink text like so: \033[38 5 206m #That is, \033[38 5 mĪnd make an early-morning blue background using \033[48 5 57m #That is, \033[48 5 mĪnd, of course, you can combine these: \033[38 5 206 48 5 57m Technology advanced, and tables of 256 pre-selected colours became available, as shown below. Generally speaking, the naming, use, and grouping of colours in human languages is fascinating. However, digging deeper into these languages shows that each uses colour in distinct ways. ( More information here)ĭifferences between languages are also interesting: note the profusion of distinct colour words used by English vs. Red appears 15 times, while yellow and green appear only 10 times. Homer’s Odyssey contains black almost 200 times and white about 100 times. It may also be why the Bible does not contain the colour blue.

This may be why story Beowulf only contains the colours black, white, and red.

If a language contains eight or more terms, then it contains terms for purple, pink, orange or gray.

If a language contains seven terms, then it contains a term for brown.

If a language contains six terms, then it contains a term for blue.

If a language contains five terms, then it contains terms for both green and yellow.

If a language contains four terms, then it contains a term for either green or yellow (but not both).

If a language contains three terms, then it contains a term for red.

All languages contain terms for black (cool colours) and white (bright colours).

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.īerlin and Kay found that, in languages with fewer than the maximum eleven color categories, the colors followed a specific evolutionary pattern. Using the above, you can make red text on a green background (but why?) using: \033[31 42m The table below lists the RGB values of the background and foreground colours used for these by a variety of terminal emulators: The standards implementing terminal colours began with limited (4-bit) options. Implementation defined (according to standard) In C++ you’d use std::cout or 2, see below To say, make text red, bold, and underlined (we’ll discuss many other options below) in C you might write: printf("\033[31 1 4mHello\033[0m")
