About The Matrix
Before we look at how to set the palette, you need to understand a few rules:
- The first four colors (0-3) are used by the Workbench for default background, text, etc and care must be taken when changing these colors.
- The next twelve colours (4-15) are used by MUI and changing these will affect many of the requesters display by the Workbench.
- The last four colours (252-255) are also used by the Workbench, and care must be taken when changing these colors.
- The remaining colours are available for general use, but they will already have a color assigned to them when you lock them or double click on them, which has the same effect.
The following example shows the kind impact that changing the Workbench colors can cause. Note that all of the free palette entries have also been locked to show their default values:
Copy enables you to copy the color of the currently selected palette entry to the palette entry you click on next. However, this will only work if the entry you click on is NOT free. You must use the Free/Locked gadget to Lock the entry prior to using this button.
Swap enables you to swap the color of the currently selected palette entry with that of the palette entry you click on next. However, this will only work if the next entry you click on is NOT free. You must use the Free/Locked gadget to Lock the entry prior to using this button.
Spread enables you to make a gradient of colors starting with the color of the selected palette entry and ending with the color of the palette entry you click on next. In this instance it does not matter whether the included palette entries are free or locked. They will be automatically locked when the Spread button is pressed.
Undo undoes the last change made. This means that if you click on it again the changes just undone will be redone.
Restore will return the entire palette to the state it was when the Palette Preferences editor was invoked.
Free/Locked gadget changes the current palette entry from one mode to the other. Locked entries can have a specific color assigned to them, while Free entries can be assigned at any time by application programs. The Workbench palette entries (0-3) and (252-255) cannot be changed - they are permanently locked. Double clicking on any palette entry will have the same effect as this gadget.
Color Allocation Map
Pressing the 'Ctrl' key changes the matrix to show the current screen's color allocation map (which doesn't need to match
the one you are editing), but I fail to understand the resulting display:
Action Buttons
When you make changes you can choose to 'Save' them permanently, just 'Use' them temporarily until the system
is rebooted, or you can 'Cancel' and lose all changes.
