NAME
cpicker − colormap editor for X11
SYNTAX

OPTIONS
-id id This option allows the user to specify a target window id on the command line rather than using the mouse to select the target window.
-wname name
This option allows the user to specify that the window named name is the target window on the command line rather than using the mouse to select the target window.

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 button underneath the hex label switches between the three palettes: range, narrow, and wide.
The "select" button allows you to choose another cell to edit, the "cancel" button restores the current color to its original value, the "restore" button restores all the cells of the colormap to their original value, and the "quit" button exits out of cpicker.
