Terminal Guide

Change/Read palette color

Parses text as ';' separated list. For each pair of items (color, str):

• Interpret color as index into the palette (possibly with special indexes following the proper palette). If str is '?' then this is a readback command, otherwise: parse str as color (via XParseColor traditionally) and set the palette entry color to that color.

If readback was requested responds with a sequence of the same form that would set the current color. E.g. ESC1b ]5d 434 ;3b 131 ;3b r72 g67 b62 :3a f66 f66 f66 f66 /2f f66 f66 f66 f66 /2f 030 030 030 030 ESC1b \5c 

Some terminals implement further colors after the proper palette that are reachable with this sequence. See set attribute replacement colors for details.

color formats of XParseColor:

• #rgb, #rrggbb, #rrrbbbggg, #rrrrbbbbgggg with each letter a hex-digit. Each group of letters specifies red, green and blue components. The components are shifted to full 16bit for shorter formats. (i.e. #fff is #f000f000f000)
• rgb:r/g/b where each of r, g and b specifies one primary color using 1, 2, 3 or 4 hex digits. The length of each part can be different. It is scaled to full value according to the number of digits used (leading zeros are thus significant, f is ffff, 0f is 0f0f)
• rgbi:r/g/b with r, g and b decimal floating point numbers. (format is case insensitive). This format uses a linear color intensity.
• CIEXYZ:X/Y/Z with X, Y and Z decimal floating point numbers. (format is case insensitive)
• CIEuvY:u/v/Y with u, v and Y decimal floating point numbers. (format is case insensitive)
• CIExyY:x/y/Y with x, y and Y decimal floating point numbers. (format is case insensitive)
• CIELab:L/a/b with L, a and b decimal floating point numbers. (format is case insensitive)
• CIELuv:L/u/v with L, u and v decimal floating point numbers. (format is case insensitive)
• TekHVC:H/V/C with H, V and C decimal floating point numbers. (format is case insensitive)
