+# This skin demonstrates how to use 256 colors in mc.
+#
+# As a prerequisite, you will need to:
+#   1) Have a terminal emulator that supports 256 colors (a few examples:
+#      xterm, Gnome terminal and other VTE derivatives, KDE's Konsole;
+#      iTerm for Mac OS X, PuTTY for Windows).
+#   2) Adjust your TERM variable accordingly, e.g.: export TERM=xterm-256color
+#      Verify by running tput colors
+#
+# Each of the 256 colors has two names, you can use whichever you prefer.
+#
+# One possibility is to use the names "color0" to "color255" to access every
+# color directly based on their number.
+#
+# The first 16 colors ("color0" to "color15") can also be specified by their
+# names (these names are already being used by mc for 8/16 color terminals):
+#   black      gray
+#   red        brightred
+#   green      brightgreen
+#   brown      yellow
+#   blue       brightblue
+#   magenta    brightmagenta
+#   cyan       brightcyan
+#   lightgray  white
+# Note that with 8/16 color terminal settings (such as TERM=xterm), colors
+# of the second column can only be used for the foreground, and their actual
+# interpretation varies across terminals. Some terminals show the colors
+# from the first column instead (that is, you only have 8 colors), but make
+# them bold. Others show the brighter version (16 foreground colors). Yet
+# others make them bold and bright at the same time. Switching to 256 colors
+# should end this ambiguity: you should have 16 separate colors according to
+# their names, none of them are bold by default but any of them can be
+# switched to bold, and all of them are available for background, too. This
+# is the intended behavior, the actual behavior might vary across terminals.
+#
+# Colors of the 6x6x6 cube ("color16" to "color231") can alternatively be
+# referred to as "rgb000" to "rgb555", all three digits ranging from 0 to 5,
+# corresponding to the R, G and B color components.
+#
+# The 24 grayscale colors ("color232" to "color255") have the aliases "gray0"
+# to "gray23".
+#
+# In addition to the 256 colors, the special word "default" means the
+# default foreground or background color of your terminal, while "base" means
+# mc's main colors. A missing value means falling back to the _default_ of the
+# given section.
+#
+# Following the foreground and background colors, the third (optional) value
+# can specify special attributes to enable. Valid values are bold, underline,
+# reverse and blink. Append more with a plus sign, e.g. "underline+bold".
+# Leaving the field empty makes it fall back to the attributes of _default_.
+# Use any other word (e.g. "none") to prevent fallback and disable all flags.
