DESCRIPTION
Cpicker makes temporary changes to the installed colormap, allowing
the user to observe the effects. It's useful for trying to pick that
perfect color or find the appropriate color combination for an
application.
When cpicker first starts, it either uses the colormap of the window
specified, or asks you to click on the window whose colormap you wish
to edit. Then, it displays a grid of the color cells in the installed
colormap. Click on the cell you wish to edit. Then, in the upper
right there will be a box containing the current color along with a
label showing the current RGB values in X11 hex format.
To adjust the current color you can use one of the nine sliders, each
controlling one of the RGB, HSV, or CMY values for the current color.
Or you can click on a cell displayed in the palette to use its color.
The palette button underneath the hex label switches between the three
palettes: range, narrow, and wide. You can also click on the hex
label to directly enter new RGB hex values.
If you click on the "match" button, the palette will change to the
colors in the file /usr/lib/X11/rgb.txt which are closest to the
current color. As you select these colors, their names appear below
the bottom buttons. Use the palette button to return the palette to
an ordinary selection.
The "select" button allows you to choose another cell to edit, the
"cancel" button restores the current color to its original value, the

original value, and the "quit" button exits out of cpicker.
