+WeeChat can use up to 256 color pairs to display text in bars and chat area
+(your terminal must support 256 colors to use them in WeeChat).
+
+According to value of 'TERM' environment variable, you may have following limits
+for colors in WeeChat:

+|========================================
+| $TERM | Colors | Pairs ^(1)^

+| "screen" | 8 | 64
+| "screen-256color" | 256 | 32767
|========================================
+
+[NOTE]
+^(1)^ Even if your terminal supports more than 256 pairs, only 256 pairs can be
+used in WeeChat, because of a ncurses limitation.
+
+You can run `weechat-curses --colors` or use command `/color` in WeeChat to
+display limits for your environment.
+
+Some recommended values for 'TERM' if you want 256 colors:
+
+* under screen: 'screen-256color'
+* outside screen: 'xterm-256color', 'rxvt-256color', 'putty-256color',...
+
+If your 'TERM' variable has wrong value and that WeeChat is already running,
+don't panic! You can change it without restarting, thanks to script 'shell.py':

+According to your terminal, 64 or 256 pairs are defined by WeeChat, a
+combination of foreground with background colors:
+
+* for 64 pairs: 8 foreground colors * 8 background colors (dark colors)
+* for 256 pairs: 16 foreground colors * 16 background colors (8 dark colors and
+ 8 light colors)
+
+Use command `/color` to see default colors (on buffer you can press 'alt+c' to
+switch between WeeChat and terminal colors).
+
+You can override some color pairs (a pair is foreground + background) with
+command `/color`, which creates option in section 'palette' of file
+'weechat.conf'.
+
+For each color defined, you can specify:
+
+* foreground and background, using format "fg,bg": color for text and
+ background, by default it is color pair number on default background (-1)
+* alias: you can give a name to your color, for easy use in color options
+
+For example, to define pairs 225 to 240 with colors like blue, cyan, green,
+yellow, orange, red, pink, purple:
+
+----------------------------------------
+/color add 225 18,-1
+/color add 226 20,-1
+/color add 227 27,-1
+/color add 228 39,-1
+/color add 229 51,-1
+/color add 230 49,-1
+/color add 231 47,-1
+/color add 232 82,-1
+/color add 233 154,-1
+/color add 234 226,-1
+/color add 235 214,-1
+/color add 236 202,-1
+/color add 237 196,-1
+/color add 238 199,-1
+/color add 239 201,-1
+/color add 240 176,-1
+----------------------------------------
+
+See `/help color` for other examples.
+
+[IMPORTANT]
+Colors defined are overriding default WeeChat color pairs, so you should
+redefine pair only if you're not using this color in WeeChat.
