Package: kbd
Version: 1.15-1ubuntu4
Severity: wishlist
I just uploaded this change to Ubuntu's kbd package, and I thought it prudent
to send it upstream to Debian as well, as I suspect some Debian users might
appreciate this utility.
I (co-)wrote a tool, /sbin/setvtrgb, that uses a clever ioctl() to dynamically
adjust the virtual terminal's (console's) 16-color color map. There's a
manpage included in the diff that explains how to (very simply) use the tool.
A separate upload to another source package (console-setup) in Ubuntu will
install a distro-recommended (though user-adjustable) conffile with an
attractive palette and an upstart job that applies the configuration on boot.
Debdiff attached. Thanks!

+.SH NAME
+setvtrgb \- set the virtual terminal RGB colors
+.SH SYNOPSIS
+.B setvtrgb
+.I vga|[FILE]
+.SH DESCRIPTION
+The
+.I setvtrgb
+command takes a single argument, either the string "vga", or a path to a file containing the red, green, and blue colors to be used by the Linux virtual terminals.
+
+If you use the FILE parameter, FILE should be exactly 3 lines of 16 comma-separated decimal values for RED, GREEN, and BLUE.
+
+To seed a valid FILE:
+ cat /sys/module/vt/parameters/default_{red,grn,blu} > FILE
+
+And then edit the values in FILE.
