Customize colors

buku allows you to customize the color scheme via a five-letter string, reminiscent of BSD LSCOLORS. The six letters represent the colors of

• index
• title
• url
• description/comment/note
• tag

respectively. The five-letter string is passed in either as the argument to the --colors option, or as the value of the environment variable BUKU_COLORS.

We offer the following colors/styles:

Letter	Color/Style
a	black
b	red
c	green
d	yellow
e	blue
f	magenta
g	cyan
h	white
i	bright black
j	bright red
k	bright green
l	bright yellow
m	bright blue
n	bright magenta
o	bright cyan
p	bright white
A-H	bold version of the lowercase-letter color
I-P	bold version of the lowercase-letter bright color
x	normal
X	bold
y	reverse video
Y	bold reverse video

The default colors string is oKlxm, which stands for

• bright cyan index
• bold bright green title
• bright yellow url
• normal description
• bright blue tag

Note that

• Bright colors (implemented as \x1b[90m–\x1b[97m) may not be available in all color-capable terminal emulators;
• Some terminal emulators draw bold text in bright colors instead;
• Some terminal emulators only distinguish between bold and bright colors via a default-off switch.

Please consult the manual of your terminal emulator as well as the Wikipedia article on ANSI escape sequences.
