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.

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.

Famous quotes containing the word colors:
“Thought maps existence; fantasy colors it.”

Change shapes with Proteus for advantages,
And set the murderous Machiavel to school.”
—William Shakespeare (1564–1616)

—Abraham Lincoln (1809–1865)
