| Intensity | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |

There are two other color standards CSS/HTML standard colors and X Window colors which standardize both the color names and associated RGB color values, but the escape sequence standard only specifies the color names, not RGB values. The chart below shows default RGB assignments for some common terminal programs, together with the CSS and the X-Window colors for these color names.

The VGA column denotes the typical colors that are used when booting PCs and leaving them in their classical 80×25 text mode. The colors are different in the EGA/VGA graphic modes.
In July 2004, the blue colors of xterm changed, RGB (0,0,205) → (0,0,238) for normal and (0,0,255) → (92,92,255) for bright. As of 2010, old xterm versions still linger on many computers though.
Recent-enough versions of KDE's Konsole program support 24-bit foreground and background color setting:

Famous quotes containing the word colors:
“Nature always wears the colors of the spirit. To a man laboring under calamity, the heat of his own fire hath sadness in it.”
—Ralph Waldo Emerson (1803–1882)
“How comes it that you curse, Frere Jean? It’s only, said the monk, in order to embellish my language. They are the colors of Ciceronian rhetoric.”
—François Rabelais (1494–1553)
“Language as a real thing is not imitation either of sounds or colors or emotions it is an intellectual recreation and there is no possible doubt about it and it is going to go on being that as long as humanity is anything.”
—Gertrude Stein (1874–1946)
