Colors can be used to differentiate between items with different values for a particular aspect as in the fourth screenshot in the example "Project planning".
There are 3 color schemes:
And the "Primary" scheme:
You determine which color scheme is to be used by an aspect when you define an aspect.
Please note that some combinations of colors and graphical options are illegible, like "15" and "16" in the "User's" palette when "Rounded rectangle" is used.
In the view which you want to improve by using colors, choose "View | Color scheme...". Choose the required aspect in the dialog.
In the fourth screenshot of "Project planning", all of John's items have one color, Sue's have a second and Alex' have a third. A fourth color is used to indicate that an item has no value for the aspect "Who".
A column view where the aspect "Who" defines the columns, and the same aspect defines the colors, must of course have columns full of items with the same color:
That's sort of trivial, whereas a column view using different aspects for the columns and colors tells you a great deal about your information without you having to READ too many details:
Here it is easy to see that John is working on his own in week 40, and otherwise doesn't have anything to do. Possibly not an ideal situation.
Left-clicking a button in the color legend changes all the selected items so they have the value shown on the clicked button. So in the screenshot above, if "Program GUI" and "Coordination" were selected, and the user clicks the "40" button at the bottom of the screen, then those two items will be changed so they should be carried out in week "40".
Changing a color
A right click on a button in the color legend allows to to choose the color for that button.
(This dialog may take a couple of seconds to appear completely). Click on one of the colored squares in the top half of the window to select that color, then on "OK".
