Changing the current host session colors

This help file describes how to change color settings for your host session. For an overview of host session color settings, refer to Understanding session colors.

To change the colors of screen elements, take the following steps:

  1. Either select the attribute on the left side of the window or click an area of the screen to automatically select the attribute. The color mapped to that attribute appears in the Sample box. The available categories and elements are listed under 3270 attributes, 5250 attributes, and VT attributes.
  2. For Java 1 browsers, to select a new color, click the desired color in the color bar. To change to an exact color, click the custom color icons to set RGB (red, green, and blue) values. For Java 2 browsers, select the desired color from the Foreground and Background color drop-down menus. If the color you want is not listed, click the custom color icons to the right of the foreground and background fields to choose a new color. This window provides a variety of color selections capable of producing a range of contrast levels and allows you to select custom colors based on their numerical values for hue/saturation/brightness values and red/green/blue values.

    You can select the attribute Other > Screen Background to set the background color for all of the screen elements at once. Any background color setting for the individual elements of the screen overrides the Screen Background color. The sample box shows the actual background color being used.

    If you wish to set the background for a particular screen element to the color black, but have the Screen Background set as a non-black color, you can do the following:
    1. Set your screen background to the desired color.
    2. Set the desired element background to a Custom Color with a RGB of 1-0-0. You cannot use true black (RGB value 0-0-0) because black indicates that the Screen Background color should be used.

    You can select the attribute Other > Active Field to set the foreground and background colors of the field where the cursor is currently located. This color setting is not applied to protected fields. It is available for all terminal types except VT.

    You can select the attribute Other > Crosshair Ruler Color to set the color of the Crosshair ruler.

  3. Click OK to accept changes made and return to the session. Click Cancel to cancel all changes and return to the session. Click Undo to undo the most recent change. Clicking Undo repeatedly will undo all recent changes in the order they were made, up to the point of when changes were started. Click Reset All to overwrite the profile customized colors to the program default colors. The Reset All changes can be undone with the Undo button.
  • The color mappings you specify will be used each time you launch the session, and they will not affect the color settings for any other session.

Import and Export Options

With this new enhancement, you can export the Z and I Emulator for Web session color remap definitions to either the current session or a file on your local system. Similarly, color remap configuration data can be imported from a file to the Z and I Emulator for Web session. The Color Remap GUI panel provides both Import and Export buttons. Clicking on each button launches a file selection panel that can be used to import and export color remap configuration data. By default the file name will end with .col extension. If you manually type the file name in the field and do not specify a .col extension Z and I Emulator for Web appends the file extensions to the file you specify.
