grabc - 1.1+git20210125.b9e4316-2+b1 main

grabc is simple but useful program to determine the color string in
hex or in RGB components by clicking on a pixel on the screen.
When this program is run, the mouse pointer is grabbed and changed to
a cross hair and when the mouse is clicked, the color of the clicked
pixel is written to stdout in hex and the R, G, B components are
written to stderr.
.
This program can be useful when you see a color and want to use the
color in xterm or your window manager's border but no clue what the
name of the color is. It's silly to use a image processing software
to find it out.
