Introduction

    Xcolmix is a color mixer, that enables you to mix your own colors in order
    to determine three values (the R/G/B code, or red-green-blue mix) of a
    color. You can use those colors to, e.g., define the foreground or
    background of X applications which support it. Furthermore, xcolmix lets
    you retrieve RGB values from the X system's database of `predefined'
    colors.


Obtaining xcolmix

    You can ftp the xcolmix package from the site ftp.icce.rug.nl, directory
    /pub/unix, file xcolmix-X.YY.tar.gz, where X.YY stands for a version
    number, e.g., 1.00. The archive extracts using tar and spills into a
    subdirectory xcolmix. It is suggested that you extract the archive in a
    `sources' subdirectory, say /usr/local/src:

	cd /usr/local/src
	tar xvzf ...../xcolmix-X.YY.tar.gz
	cd xcolmix

    Get the XForms library and headers. See the Makefile in the src
    subdirectory, extracted from the archive. Then, edit the Makefile
    following the directions stated therein and `make install'.


Using xcolmix

    Xcolmix lets you define a separate background and a foreground color for a
    part of the mixer window (the logo). Use this logo to, e.g., compare
    whether a particular text color looks good on a particular background.

    Use the `foreground / background' buttons to select between the foreground
    or the background. Then, use the three silders labelled `red', `green' and
    `blue' to change the color.

    The button `lookup' starts a second window, with a browser showing the
    system color database. The default database name is /usr/lib/X11/rgb.txt,
    though you can overrule this filename with a file argument in the command
    that starts up xcolmix.
